The best results I've had (using a Matrox G400 16MB), with Heretic2 and
Soldier of Fortune (and a few demos e.g. Heavy Gear and Quake) have been
with X3.3.6 and utah GLX.  Heretic didn't like X4 and sof needed alsa,
which I wasn't happy with on kernel 2.4.1 - jittery sound and

The X3.3.6 & utah glx ran ok in 32bpp at 1600x1200 whereas X4 won't, at
least with only 16MB on the G400, so I have to switch XF86Config-4 files
(32/24-16)(symlinks) to get DRI running.  Then it's ok.
