We did have another revert to fix hopefullythe last "blank screen" regression on intel graphics.
It seems that there is still a regression for intel graphic cards backlight. One report is
https://bugzilla.kernel.org/show_bug.cgi?id=22672.
I can reproduce the problem easily by:
xset dpms force standby; sleep 3s; xset dpms force on

backlight doesn't get up (there is really dark picture though which doesn't get brighter by function keys which work normally) after dpms on until I close and open lid.
The problem wasn't present in 2.6.36
And I have a different regression.
On 2.6.36.2 everything is fine, on 2.6.37 my laptop's display is more or less blank, backlight on, with a white pattern slowly moving across the screen like it was a (bad) moving spot light effect.
