drm-i915-update-38, no output on high resolution display

[Stefan Wendler]

I can reproduce this. I have the same CPU and the last commit that works
for me is 10fada6d35b00431585d549f00ab609d7a3652ef

So commit 72bb3b3f9dcaf573be532ced9043eb59dedf21df introduces code that
breaks i7-4910QM CPUs

Interesting .. looks like I have started testing after this commit then ^^

thanks to Stefan Grundmann for giving the hint :)

Cheers,
Stefan
