100% agree.

But it's up and running now on my box :-)

gears is now running with about 80 fps windowed, and also about 80 fps

Thats also true :). It's roughly playable now in 640x480.

The key for me was your hint about 

TDFX(0): direct rendering disabled

Meanwhile I found a nice little program named '3Ddiag' which is located
in the pkg '3ddiag-0.149-0'. It told me that 'xf86_glx' and 'glidedri'
were missing (I didn't know about the existence of this pkgs). I
installed them and also removed the 'glide_v3-2.60-131', which collided
with one of them. I also changed a little bit in '/etc/X11/CardModules',
namely the appropriate tdfx-line into 'tdfx=Accel NoSLI HWcursor UsePIO'
(don't know whether this is a must, I located this line while searching
around). In /etc/X11/XF86Config is also a line refering glx which was
missing in the original file: 'Load  "glx"' (all without the ')

My kernel was already compiled with tdfx as module, and bingo, it runs.

Maybe this also will help with your girlfriends PC ;-).

But one small bug seems also to be in prboom, the sky is kind of
multiplied.

Thanks to all who helped
