Cheers for replying so far folks, but (and there's always a `but'...) I
think I might still be missing something.

I got the sources from the link above, and got them compiled. In order
to compile the sources I had to comment out a few lines in one of the
Makefile's so that it didn't touch the kernel drivers for other cards.
See, I'm using kernel version 2.5.34, and although it's recommended
that a 2.4.x series kernel is used, everything relevant to the mach64
chipset compiled on my kernel version.

The kernel module (mach64.o) loads quite happily when the X server is
started, and doesn't spit out any error messages. The X server seems
very happy with the DRI idea too:

"(II) LoadModule: "glx"
(II) Loading /usr/X11R6/lib/modules/extensions/libglx.a
(II) Module glx: vendor="The XFree86 Project"
        compiled for 4.2.0, module version = 1.0.0
        ABI class: XFree86 Server Extension, version 0.1
(II) Loading sub module "GLcore"
(II) LoadModule: "GLcore"

        Module class: XFree86 Video Driver

...Running glxinfo I see the appropriate lines:

"direct rendering: Yes
...
OpenGL vendor string: Gareth Hughes, Leif Delgass, Jos? Fonseca
OpenGL renderer string: Mesa DRI Mach64 20020227 [Rage Pro] AGP 2x
x86/MMX/3DNow!
OpenGL version string: 1.2 Mesa 4.0.3"

... and the /dev/dri/card0 exists with the correct permissions, thanks
to the DRI section in my XF86Config files, so all seems well and good.

So why is it that when I run glxgears it runs just as fast as it did
before I got things up to this level? The version of glquake I have
(which by all means should run, since it's not that old version of
glquake that only ran on 3dfx cards -- see
http://mfcn.ilo.de/glxquake/) runs slower than the x11 version of
quake.

I have done depmod and ldconfig's after getting everything installed,
so the problem doesn't lie there... grr ... Ideas? Suggestions?
