Just to confirm, these are fixed by
 [PATCH 1/2] drm/i915: don't disable a PCH DPLL that's in use
and 
 [PATCH 2/2] drm/i915: only set the intel_crtc DPMS mode to on if the
   mode set succeeded

right?  Or are there other patches needed as well?  Can you reply to
them with your tested-by so Keith can pick them up?

Thanks,
