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.
