Brightness applet does not work correctly on a Macbook

[Arne Caspari]

On a Macbook 1,1 , dragging the slider of the brightness applet causes the screen to flicker ( brightness is adjusted afterwards though ). Worse, if I just click on the - button to decrease the brightness, the backlight is turned off completely rendering the screen unusable.

This is tested on Intrepid ( latest updates ) and is a regression to Hardy where it worked fine.

Not to be confused with bug 457882, where the brightness is not adjustable at all in Ubuntu 9.10 and later.

On Jaunty, this problem is stil present. (This install is upgraded from intrepid)

I'm attaching the output from running (the gnome-power-bugreport.sh I copied from an intrepid install) on Jaunty.
