Test with the combined revert patch.
All the HDMI mode in supported list can light up normally. 
(no 1024x768 86Hz mode in supported list)

Comment 2 Chris Wilson 2012-08-22 13:37:03 UTC

What's the current status? Didn't Adam Jackson push some refinement for the additional modes?

And hopefully it continues to remain working until 3.6!
