Getting Better Battery Life w/ Linux?

Nuclear Elephant asks: "After a little hacking, Linux has been running great on my Thinkpad T30 for about a year now. I can talk to my cellphone and bluetooth devices, do all kinds of neat hacking on wireless, and just about everything you'd expect to be able to do from a Windows machine, except make the battery last. Even after the standard optimizations (like cpufreq, laptop_mode, brightness, turning off useless processes, etc.) my battery still only lasts about an hour running under Linux as opposed to 2 1/2 hours in Windows. Has anybody come up with some innovative battery conservation ideas for Linux? It seems to be the only thing lacking in this fine operating system." What kernel options might one look into, for saving laptop battery power? Also, what desktop settings (both for Gnome and KDE) would work best, for this situation?

or... he could get a Mac.

Seriously though, Mac's are great. It's UNIX with none of the drawbacks, and is a nice GUI with none of the tedium / lack of power. Fabulous. I suppose this really doesn't help the poster though. So I'll probalby get mod'd Troll or Offtopic.
