I tried https://edge.launchpad.net/~albertomilone/+archive/x-testing on a live system (new mesa), and I still have the same problem.
When I remove /usr/lib/dri/r600_dri.so, GNOME session starts up, but with metacity. So that would be a regression compared to Jaunty, where I didn't get 3D acceleration on the r6xx, but at least compositing and Xv worked.
