Both a notebook and a desktop system suffer from the same thing: They both run on 110AC. Inverting your DC solar power to that will cost you 30-40% of your power. Converting back to DC (for your notebook/desktop) will cost you a second round of 30-40%. This is bad.
Find a method that can keep you at DC power, ideally as close to the voltages you need. Many of the mini-itx boards will have an option for 'dc power'. These will run on 12-15 volts, and will cost you more like 10-15% TOTAL. Plus, many of the mini-itx boards will consume far less power - - some of them as little as 15-20watts. You won't quite have the speed mentioned (1.7ghz), but close to it (900-1200mhz).
You could use a notebook & build a native DC supply for it - - but many of todays notebooks, regardless of size, draw MASSIVE amounts of power. My dell notebook draws 3.5amps@20 volts [70watts]. That's at 1.2ghz/512megs of ram/15" screen.
As others have pointed out, you'll need power storage. This can be calculated based on your consumption & number of panels used. You can lookup the typical number of solar hours per day for your region.
Solar panels cost around $1USD per watt. The charge controller & storage will also be somewhat costly - - do some reasearch, and purchase a few books on the subject before spending to much...
Most of the 'hams' out there are not even on the internet. Wait until they die off (soon, I'm guessing), and the newerr generation takes over. Then we'll see some cool stuff again from hams.
Currently, the ax25 stuff under linux works, but it's licences are lame (non-gpl). I had at one point a working version of tcpdump that worked with ax25 frames for ham/digital stuff, but it wasn't 'legal'.
One of the big problems with ham 'warez' are that most of it is really lame windows shareware - - most of the current tools are not free, and most don't have equiv. linux versions.
Blah, leaf has been dead & outdated for years. Everyone has moved to LEAF.
http://leaf.sourceforge.net/
This is not a loss. LRP was great tech about 4 years ago. The world moved on, and now everyone uses better tech. Really, just checkout Leaf Bearing for some current 'router on a floppy' tech, and don't even bother reading this guys poor, sad story. He's starting to sound like the CEO of enron.
Many of the chipset makers feel that their 'drivers' are also their IP. In the wireless space, the first to market folks get to make the rules. In the case of 802.11a, Atheros was the first to market.
There existed a 'binary only' driver that was built on a mandrake linux box. The bad news is the way it was built made it completely useless. I've not heard of anyone having sucuess using it. Rumor has it that Atheros built this driver & they would release 'formal' drivers for their chipsets. This hasn't happened yet. I doubt it will until they have somebody else providing 802.11a chipsets. To them, it's about getting market share & protecting IP.
Recent developments:
Reyk Floeter has started building a GPL driver. It's amusing based on the context of this article, because all this driver can do is SNIFF. That's right, RX Only. Progress has been very slow, and there have been several questions to the list as to how this driver exists, and how it's being built. It would seem that Reyk doesn't have any of the specs & hasn't signed an NDA. I assume he's reverse engineering the windows drivers, but he hasn't stated as much. The development progress has been _VERY_ slow, and this project needs help from OSS devs. Anyone up for a challenge?
Intellegraphics signed the NDA, and has a driver 'for sale'.
While the government has it's paws in everything, I doubt this is the case at this point. This whole article is based on FUD.
1. First of all, this 'airport', is really just an RG1100 with a different cover. Sure, you can connect antennas to it. But it's not a "MAC Only" think it's a "Windows thing" that just so happens to have MAC OSX drivers. Google on rg1000 + linux/windows. You'll find several java config tools. Moron.
2. Anyone who really has the title 'wireless network engineer' would know that building homebrew antennas just isn't worth the time. most of them end up sucking, and it's MUCH cheaper to just purchase one online.
3. Anyone who cared about the FCC regs wouldn't do this.
4. To do real LOS tests, you want antenna systems with known gain & radial patterns.
5. You'll want kistmet, as some other posters highly under-rated posted.
They are finally getting it. I suspect we'll see some great changes by the FCC in the coming years - - They know all about spread spectrum, UltraWideBand, etc. They know how loaded the 2.4ghz part 15 space is - - and we're going to see them open up lots of new spectrum for 'real use', not just 'on the block for sale'.
Now is your chance to move to jabber. Jabber is an open source server/client/protocol. Some of the clients even support ssl (encrypted) messages. You have to be careful, however, as the auth is still plaintext, even using ssl. But still, jabber may be a good answer: It supports 'gateways' to AIM, yahoo, etc.
Yes, but those had been filed in advanced with a 144. He had filed in advance to sell 1M on 10/22/02, but he's knocked that up to 3. And it was just minutes before the close of market. It's a shifty move.
After reviewing the list, I suspect some of this is based on how prolific the worms got for each respective hole - - IIS gets top of the list for nimda, same with apache & ssh. sendmail has had a HUGE number of security problems, but most of them had been found 'pre-wild-worm madness'. I guess this is the right way to do it - - but then it just seems like all we'd need to do to make this report is measure the amount of press during each outbreak. I'm not very impressed with this list - - it's all old news.
While I was at defconX, I fired up kismet at one point, and started see lots of APs. It turns out that the folks sitting behind me had been from Black Alchemy, playing with this neato tool. I personally saw about 600 APs/minute with this tool under kismet, and they had lots of dumb windows clients trying to associate with them. With some tuning, I'm sure they could get the number of APs per second to increase (They may have done this by the time of release).
It was good stuff, and I ended up getting my name in the credits.:)

The ARRL, who has the ear of the FCC, is currently reviewing interference from part 15 "2.4ghz" 802.11b devices.

It was a REAL pain to make it work under X. You'll need XFree86 4.2.0, and if you want ANY suspend to ram/disk to work, you'll need to disable AGPMODE in the XF86config-4 file.
That means, if you want to have DRI/GLX support, you can't have APM.
It really sucks. I hope that the drivers improve for this device. I would hold off on purchasing a notebook if you are expecting to run linux on it.
I've seen EQ stuff sell for boatloads of cold US cash on playerauctions.com. The most interesting part about EQ is the numbers - - because of the level of off-game trades & sales, it's devalued the cost of plat (EQ's monitary unit).

You just have a alphabios only system. The other 'switch to unix' option that you don't have is for booting SRM.
There is a solution: Run 'milo'. Milo (like lilo for alpha) is designed to boot from alpha-bios based systems. You should have no problems getting it to install.
Ever wonder what that 'SRPM' cd is all about? Well, it's the source to everything on your system. If your paraniod to the level of wanting to rebuild from source, then I assume you've reviewed all of the kernel source (how many lines these days?)
I'm paraniod. I run openbsd. I trust what's on the CD.
If you only have ONE command line, I don't expect your firewall to really be very effective, or flexible.
*real* firewalls (PIX, Ipf, ipchains, etc) allow you configure any aspect of the IP/ethernet traffic.
Regardless, I'd bet my lucky dollar that they use standard http[s] for sending out registration, etc. Otherwise, many corp. firewalls & proxies will block it.

Sure, someone can feed you bogus dhcp info, and they could then man-in-the-middle you.
That fine, but THIS hole (and it is a hole, not a bloody feature, IMHO), grants anyone on your subnet r00t access on your MAC.
This is a different attack completely.
AFAIK, no other OS offers root access to any little kiddy acting like a dhcp server.
