Essentially the same specs as Sybase's ASE 12.5 / 15.0 Express Edition, with the difference that Sybase doesn't stop you from running multiple instances on the same machine.
I added greylisting to my mail server, and that cut down on both spam and virus messages by a tremendous amount. See http://greylisting.org/ for more info.
Developers interested in re-distributing ASE Express Edition can contact Sybase's Business Solutions Alliance team for more information.
Essentially what they are saying is that you can become a Sybase "partner" and at that point you would (presumably) be authorized to redistribute the package.
No - of course Sybase is multi-threaded, and has been since day one (long before Oracle used threading). A multi-threaded app will only run on one CPU at a time, at least in most cases. What "engines" mean here is one or more engines that access the same set of shared memory. You usually configure engines based on the number of CPUs that are available, and each engine is multi-threaded.
If you read the Sybase document that announces this they are interested in hearing from you if you'd like to redistribute this version with an app that you've created. So it's not really that bad.
You can use this version of Sybase on a machine with any number of CPUs. The issue is that you can't configure it to use more than one CPU at a time (i.e. you can only configure one engine).
I'd like to point out that Sybase offers two "free" versions of ASE.
The "developer" edition has been available for a couple of years, and comes with a lot of the "extra" features turned on (such as Java in the database), but is limited to one engine and 25 user connections. It's also a version that you can't use for production purposes. It is available for a number of platforms (Windows, Linux, Solaris).
The new "Express" edition is (AFAIK) only available on linux, does not have the 25 user connection limits but instead has a disk space limit, and is usable in a production environment.
Sybase has various replication tools. One is shipped with this EX version (Replicator 12.5) and is written in Java (I think). Their Replication Server (not free) is probably the best replication system in the DB business, allowing you to write/create any form of multiple site replication (both master/slave and master/master). Finally, SQL Remote is part of their Adaptive Server Anywhere package and is better suited to lower volumes and to syncronize systems that aren't always accessible (such as from hand-held scanning devices).

Perl 5.8.0 Released

Nope - sybperl is still supported (although "sybperl" is just the collective name for the Sybase:: modules for perl 5)
Sybase may have a relatively small market share, but they are definitely the major player on Wall Street and for a lot of Telecoms. They have 60% (at least) of the mobile market (with Adaptive Server Anywhere).
In terms of features, Sybase has a lot of functionality for the DBA that Oracle still doesn't have (like rebuilding indexes without locking the table, or simple on-line backups).
And Sybase is very scalable and in general out-performs Oracle on the same hardware.

In what way is DBD::Sybase lacking?

Note that there is a free version of Sybase for linux. See linux.sybase.com for details.
