Spurious TV detection is still here and + I have a new problem with
resolution in init3 when KMS fires up, it occupies only 1/3rd of the
screen when booting.

I've tried patching the kernel I used for testing so far with that one
liner and I've tried without patches we tried so far (git pull on a
clean linux-git) and the symptoms are the same on both of them.

So
- PIPE_VBLANK_INTERRUPT_STATUS) == 0,
+ PIPE_VBLANK_INTERRUPT_STATUS),
in intel_display.c doesn't fix the issue, plus it brings a new one in my
case.
