Brightness setting in Screen does not persist across reboots

On my Lenovo Thinkpad T430, when I adjust the Brightness setting in the Screen preflet, it does change to the level I set. However, after I reboot my machine, the brightness returns to the full intensity. Until Haiku has an auto-brightness manager, the brightness should be saved in the appropriate settings file upon close of the Screen preflet. When starting up, Haiku should read the setting and apply the brightness setting that was previously being used.

Yes, currently the setting is just read back from the video card, there is no storage anywhere. This should probably be stored in the screenmode settings and restored by app_server when setting the video mode.
