Everything was set up properly for my Voodoo3 AGP card in the XF86Config-4,
with the exception of the DRI Mode. After adding 

Mode 0666

to the DRI subsection and restarting X, everything seemed proper, except 3D
was still rendering slow. After some investigation it appears that tdfx_dri
is *NOT* part of the XFree RPMS, and should be. 

Reproducible: Always
Steps to Reproduce:
1. Install Fisher on a system with a Voodoo3
2. ls /usr/X11R6/lib/modules/dri
	

Actual Results:  No tdfx_dri module present, ligGL cannot load tdfx dri
module, 3d perrformance is hampered. 

Expected Results:  tdfx_dri.sso should be loaded by libGL, accelerating the
3D calls. Compare a 3D screen saver (I use atlantis) with & without 3D
accel.

If this is to be included as an "extra" a-la 7.0, that's OK, just document
it better this time!

Also reproducable on wolverine.
