Actually it seems like this is pm-suspend writing bl_power=1 which promptly
switches the backlight off as requested. (Before you ask, bl_power=0 is on,
other values off.)

However I can't find a version of pm-utils that touches bl_power by default.
Which version are you running? Distro? Or is that your own addition?
