I've been having some problems with my main development machine, so I'm upgrading to a 2.4 kernel to see if that will solve some of my problems. Here is the proof that I'm getting old and crotchety: I used to enjoy fiddling with system, but now it just seems like a drain on my time.
Still, I'm eager to see the extent to which SMP performance is better. And for the first time I've got DRI working; now all I need are some OpenGL apps...
