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.
