2.4 drm code for mach64 can be easily ported to 2.6, I did it some time
ago, there is the patch for 2.6.10 (should work for other 2.6.x):
http://rainbow.mimuw.edu.pl/~mb197846/DRI/drm-2.6.10-20050220.patch.bz2
original code taken from:

(You need to copy .o and .so files to /usr/X11R6/lib/modules/...., do
not run install.sh script!)

For DRI acceleration you need kernel module (the code is in
drivers/char/drm/), which is an interface to graphics hardware,
and appropriate Xfree86/X.Org module
(/usr/X11R6/lib/modules/dri/mach64_dri.so), which uses this interface.
Dri is currently developed in X.Org tree, so if you want newest
features, you have to compile X.Org too.
The easy way is to install packages from:
http://www.nixnuts.net/files/
but this means installing X.Org, and (on my ATI Technologies Inc Rage
Mobility P/M AGP 2x (rev 64) ) glxinfo shows: direct rendering: No
