Bug Description
After upgrading to Jaunty brightness settings are not remembered anymore when rebooting or when disconnecting power cable.
During boot process brigthness changes multiple times:
- at BIOS screen brightness gets correctly restored to last used one
- when ubuntu starts loading brightness is increased (to maximum level?)
- when gnome-power-manager starts it is set to maximum no matter what level it was set last time and doesn't even care if the laptop is on battery or on power cable.

Confirming the issue for gnome-power- manager: it sets brightness level to 100 as soon as it starts.
There is still something else that does the same while ubuntu is loading but still I don't know which package.
