Hi,

sorry for the late reply, I'm quite busy at the moment.

Okay, I've played a bit with pm-suspend and its --quirks-* options.
Here are my results:

none:
 + backlight on
 + no resume  

dpms-suspend:
 + backlight on
 + resume

dpms-suspend + radeon-off:
 + backlight off
 + no resume

radeon-off:
 + backlight off
 + resume

So if I drop dpms-suspend, everything is okay, it's just the current
combo of radeon-off AND dpms-suspend which breaks things for me.
My 2672PG9 is a bit moddified (Intel 2915 Wifi and Bluetooth), but both
are off during my tests, so they should not hurt.

@Anarcat + Antony:
Can you two try to suspend with "pm-suspend --quirk-radeon-off" and
tell me if it resumes fine and has backlight off during suspend?

Regards
Evgeni
