maybe i missed something, but i dont see the core validating the .type value at registration time. since the value is then used later as an index into an array, shouldnt it verify that it is valid ?
do you want to force everyone to declare they're "raw" ? or just go with the memset default to have people start with "raw" ? otherwise it might make sense to have the first enum be BACKLIGHT_UNKNOWN and have the core warn when it hits that.
