On some systems acpi-video backlight is broken in the sense that it cannot
control the brightness of the backlight, but it must still be called on
resume to power-up the backlight after resume.

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
special there.

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

Regards,

Hans
