Backlight doesn't come back on after resume
Until recently, I was able to get video working again after resume if I passed acpi_sleep=s3_mode and had a script that changed away from and back to my X session (the framebuffer was screwed afterwards, but never mind). This seems to have stopped working recently - in 2.5.70, I end up with a machine that pings, but no video. I've tried all permutations of acpi_sleep and using or not using the framebuffer. It worked in 2.5.65. Anyone have any idea what might have changed?

Oops. Hitting the video output key a couple of times seems to have fixed this. 2.5.70 seems to let me do S3 suspend/resumes repeatedly - I've just done 5 of them without any trouble. Great work!

Try to find out which change broke it.
