Wait, this regression has nothing to do with backlight control. We already
have backlight drivers for platform specific or ACPI interface, the reason
intel driver doesn't hook up one is because if we provide native interface
which would be much possible to have state conflict with platform or ACPI way. 

This problem is just the wrong DPMS state is used for FB blank request.
Dave, does my patch look sane? This regression isn't in 2.6.32, but only
for .33-rc kernel.
