Bug description:
  Binary package hint: gnome-power-manager

  Versions : karmic up to date (08-17-09) with gnome-power-manager
  version 2.27.5-0ubuntu2

  What should happen : brightness should not flash.

  What happens :

  Brightness changing seems broken on my MSI wind U 100.

  First in GDM it starts flashing for a good 30 seconds and then the
  same problem happened when the Gnome session begins.

  Whenever I try to  manually change the brightness  a bit too fast
  (using the sliders or the keyboard) it start flashing again.
