On some systems acpi-video backlight is broken in the sense that it cannot

All the video module does on resume is a backlight set operation, it
can't control backlight but can turn on the screen on resume? Hmm...
I'll ask Sylvain to attach acpidump, let's see if there is anything

Ok, lets see what comes out of that. Note in the mean time Sylvain has
attached his acpidump.
