I can confirm this fixes the corruption I've reported in bug 97610.

Since Marek mentioned in the commit message of the revert, that it's maybe some
tile configuration issue, I was wondering if Tom was correct in bug 97610,
comment #1? Should I do the test – obviously with the revert undone – with the
tiling configurations copied from radeon (bug 97610, comment #2)? Or is this
something else?
