[Intel-gfx] Regression: bisected: commit 7c510133d93 breaks video

[Paul Zimmerman]

I have an ASUS P6X58D-Premium mobo with a GeForce 9400GT PCIe video card.
With kernel 3.12-rc1, I get scrambled video on boot. Kernel 3.11 works
fine.

Bisecting this, I found 7c510133d93dd6f15ca040733ba7b2891ed61fd1 "drm:
mark context support as a legacy subsystem" is the guilty commit. If I
revert that commit, the video works fine.

Is there any more info I can provide?
