Rather than signaling a full update of the display from userspace via a console switch, this patch introduces 2 files int /sys/power, wait_for_fb_sleep and wait_for_fb_wake. Reading these files will block until the requested state has been entered. When a read from wait_for_fb_sleep returns userspace should stop drawing. When wait_for_fb_wake returns, it should do a full update. If either are called when the fb driver is already in the requested state, they will return immediately.
