This is NOT officially released but since the 2.3.28 development kernel there
are two drivers included. DRM, the general device driver of DRI and the
special driver for the GMX2000 (two layer architecture). I've folded the DRM
and tdfx module taken from the mentioned 3dfx side into the prerelease of
2.2.14. Now I am working on the inclusion of tdfx into 2.3.28+ and I am still
in contact with Daryll Strauss (PI) and Joseph Kain (3dfx).

Have I told you that I can play q3test-1.08 with ~43 fps in a 800x600 window
besides some (several) vtk OpenGL contexts?

Do you want some screen shots?
I could send them if I am back at home.
So please CC to my home address.

Regards,
        Dieter
