The default on my laptop is annoyingly bright, and this is a useful feature to mitigate that. The backlight script is largely a copy of the mixer service which provides the same value for mixers, but this one is specifically dependant on kld to allow DRM drivers a chance to attach. Note that it's off by default to avoid interference with DEs, and document the capability in backlight(8). Set backlight_enable=YES in rc.conf(5) to enable save/restore.
