The R128 will do DRI, the Mobility Pro (which I believe is a
Mach64-derived design) will not - at least, not yet. Support for
Mach64-based 3D-enabled cores is in the works.

That's right - because the r128 DRM uses the AGPGART interface.

It's never a module, it's either built into your kernel or it's not. If
/proc/mtrr exists, then (a) it's built into the kernel, and (b) your CPU
supports MTRR (it's a CPU feature - K6-2s stepping 8 and up, K6-3s,
Athlons, some Cyrix chips, and P2/P3/P4 (including Celerons) have MTRRs or
a close analog).

It looks like you may need to add a line that says 'Load "dri"' in your
Module section. Otherwise the X server itself doesn't know about DRI, or
the setup for it or anything else.
