Bug#846941: linux-image-4.8.0-1-amd64-unsigned: ThinkPad X220: hibernating with screen turned off (screensaver) causes it to remain off until reboot

I had temporarily disabled screen power management in XScreenSaver and
have been hibernating via `echo disk > /sys/power/state` for a while.
After a few hibernate-resume cycles the system rebooted instead of
properly waking up after loading the image, so that's not uswsusp's bug.
However, it might deserve a separate bug report.
Also, the only reason s2disk doesn't cause the system to wake up with
screen disbaled is that it switches to another console before
snapshotting the system, forcibly turning the screen on.
