GLX is already included in XF 4.0. GLX is a glue that holds X and a GL
renderer together.

utah-glx is a bit of a misnomer, since most of the developement work is
done with the low-level hardware rendering drivers, not higher level GLX
server-client stuff. GLX uses Mesa library. Any applications compiled
for use with Mesa can take advantage of using your hardware for
rendering, if supported.

DRI allows bypassing network pipe in X for the data going to your card,
resulting in better performance. So it's something like Application->GLX->DRI>Hardware. Please correct me if I am wrong.
XF86 4.0 only supports 3Dfx for hardware rendering. 4.01 should include
utah-glx which will provide support for Matrox NVIDIA and Rage Pro
cards. You can use utah-glx right now to play Q3 Arena, and it runs very
nice already even on my 4MB Rage Pro card with XF86 3.3.6.
