well, it won't work until you are using a new enough version of the
the drivers.  At this point you need to use the cvs versions of all
three (ddx, drm, mesa) to get direct rendering on r3/400 class
hardware.  The version of X that ship with most distros (6.8.x) does
not support 3d on your hardware.
