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.
Thanks. According to the discussion in the bugzilla place, it doesn't seem we have any other way to handle this at the moment.
