A snapshot of the aforementioned r6xx/r7xx code is now uploaded to ubuntu. The kernel changes have not yet gone in, so full support for these chips won't be available until that happens (perhaps in a few days).
Again, 3d/compiz support is not supported with this release, although I've added the chip registers to mesa so it's possible some 3d features may work.
