<pre>I have also bisected the kernel between 3.6.0 and 3.7.0:

drm/i915: fixup the plane->pipe fixup code
We need to check whether the _other plane is on our pipe, not whether
our plane is on the other pipe. Otherwise if not both pipes/planes are
active, we won't properly clean up the mess and set up our desired
plane->pipe mapping.
v2: Fixup the logic, I've totally fumbled it. Noticed by Chris Wilson.
v3: I've checked Bspec, and the flexible plane->pipe mapping is a
gen2/3 feature, so test for that instead of PCH_SPLIT
v4: Check whether we indeed have 2 pipes before checking the other
pipe, to avoid upsetting i845g/i865g. Noticed by Chris Wilson.
