I'm not sure whether that's an r128 chip or a mach64 chip - if it's
the r128, the standard XF86 4.1 packages should give you DRI based
support for hardware 3D. If it's a mach64, then you'll need to grab
the DRI cvs code, and that means installing XF86 4.2, as well . . . 

The place to look for the right information is at http://dri.sf.net.
More specifically, the Help and FAQ link from the front page. The
dri-users and dri-devel mailing lists are good places to ask
questions, too. 

Just as a starting point, look at your /var/log/XFree86.log file,
and grep for 'DRI' - if it's being loaded, you'll see a couple of
things mentioning it, including the XFree86-DRI extension (which you
can also check for with xdpyinfo). Also, you should see a kernel
module loaded - r128.o or mach64.o, depending on the chip. 

So, check xdpyinfo for the XFree86-DRI extension, check for the
kernel module, and check /var/log/XFree86.log, in that order, to see
where things are now. Then read the DRI user's guide, and hopefully
you'll be able to solve your problems.

Good luck,
