I'm on 3.9-rc7 now and backlight control does not work at all unless I issue
'echo 0 >
/sys/class/backlight/intel_backlight/brightness'.  If I issue 'xset
dpms force off', it breaks again and issuing 'echo 0 >
/sys/class/backlight/intel_backlight/brightness' fixes it again.  Would it
still be helpful for me to turn up debugging?
