Title:
  backlight brightness control won't work in 2011 iMac 27"

Status in “gnome-power-manager” package in Ubuntu:
  Confirmed

Bug description:
  When I press the 'Brightness Control(UP, DOWN)' key in Apple Keyboard,
  the OSD shows Increasing Backlight(or Decrease) at the right-top corner.
  But the Screen Brightness doesn't changed. 

  Also, I waited 15 minutes, the screen turned black. (Power Setting)
  But the Backlight still alive.

  This iMac has AMD Radeon HD 6970M.
  I think maybe it's because the driver doesn't exist in kernel module.

  Sorry about my poor English and few information.
