Hmm, looks like the brightness control screws up on your powerbook.
Any chance to telnet/ssh into the powerbook and play with wsconsctl,=20
checking if it's able to change brightness? Some radeons have=20
brightness levels reversed ( 255 is dark, 0 is full brightness ) - my=20
iBook for instance - while others don't. My guess is we get it wrong on=20=

yours.

have fun
