It depends on how do you see it :) brightness_default is the value that brightness will have at the next (and later) reboot and it's currently handled as a platform_device attribute. It would be nice anyway if one such attribute could be added to the backlight subsystem (I'll provide patches - added rpurdie to the Cc list) in order to standardize its behavior/interface. -- mattia :wq!
