Yeah, me too which is why I am doing a git bisect here. What's strange about it is that the first bisection point seems to suggest that the regression happened _before_ the DRM merge to 2.6.33-rc1. I guess it's possible that the bug is already in 2.6.32 but I've yet to see the flickering effect. Oh well, back to bisect...
