I have a Dell Inspiron 6400, and I confirm this bug after a day of debugging gnome-power-manager. Both gnome-power-manager and the kernel/BIOS/something-that-is-not-gnome-power-manager try to change the brightness when I press the brightness keyboard keys.
How about adding a HAL property that indicates whether the BIOS controls the backlight, and have gnome-power-manager not adjust the backlight (and let the BIOS do it) if this property is true?
