It seems to fix the problem, but I'm not certain, because the behaviour started to become much less obvious after I sent this bug report (but before I tried your diff). I would see the occasional short flicker rather than reversions lasting nearly a second. With your diff I haven't seen any flickers. Going back to the Sep 9 snapshot kernel (which I was using when I filied this bug) I tried to find things that would trigger the problem the reliably, so I could try the same things with your diff, but I couldn't find a way to trigger it. (Mostly I just tried vigorously scrolling in Firefox assuming taxing the graphics card would trigger it, but that didn't work.) -- James
