Does this patch help?

Yes! That patch eliminates the problem (and current git as of v2.6.37-rc5-26-g2cedcc4 still has the issue, without the patch).

As mentioned, this has affected stable 2.6.35 and all of 2.6.36 as well, so applying this to the stable tree for both should be considered as well as 2.6.37, once you're sure it's unlikely to cause other problems.

FWIW, with the patch applied, I'm getting the best and most glitch-free OpenGL accel I've ever seen on this hardware. It's quite nice not to see or know of a single glitch. Now /this/ is what I purchased this r7xx Radeon upgrade for! =:^)

And, even tho there were a couple glitches still and I had that one commit revert, I had an uptime of nearly a month on 2.6.37-rc1-170-gf6614b7, before I rebooted to test current, so everything's pretty stable too, it seems. 2.6.37 might well be the best kernel I've seen in awhile. Certainly, I don't believe I've seen that sort of stability just after rc1 for some time. =:^)
