The HOWTO you said you thought you found.

Is r128 compiled in, or a module?  It should be a module.  You'd also
need the AGP module for your chipset loaded, since DRI requires AGP.
I sold my r128-using machine 1.5 years ago, so I can't reproduce its
config file, but I had to modprobe intel_agp and r128 before DRI would
work.  Find out your AGP chipset and make sure its support module has
been modprobed before X starts.  That's in /etc/modules.autoload.d/ 
for Gentoo users, YDistroMV.

Right now, 3D is much easier with nVidia cards and the evil
binary-only modules than it is with ATi cards.
