What about the current 7.11 branch? If that still shows the display errors, you should be able to bisect the change that fixed it on the master branch.
No bisection required. The bug was fixed by this commit:
"r600g: set correct tiling flags in depth info" http://cgit.freedesktop.org/mesa/mesa/commit/?id=faa16dc456f1f910eef24eaa238...
which I just verified by re-compiling mesa with the reversed patch applied.
