Mesa 7.6 has the new r600 DRI driver (with 3D hardware acceleration). AFAIK, this driver still needs special DRM kernel modules (from Alex Deucher's branch of DRM: http://cgit.freedesktop.org/~agd5f/drm/?h=r6xx- r7xx-3d ).
If you want to test this out, try mesa 7.6 again and temporarily move the file /usr/lib/dri/r600_dri.so Now when you start X, mesa should fall back to using the DRI software rasterizer (check glxinfo) and your system should work normally. You could also build your own DRM, though the r600 DRI probably isn't ready for "stable" use.
