If you are running debian or ubunutu you can grab packages here:

Otherwise you'll have to build everything from source.  You'll need:
drm git master (both kernel components and libdrm)
mesa from the r500-support branch in git
xf86-video-ati from git master.
xserver from git yesterday or before (prior to the swrast dri changes)
