No BACKLIGHT for

[Richard Hughes]

Sorry to open an old wound, but it looks like radeon won't be adding
BACKLIGHT into the driver, ever.

Unless we can convince Alex otherwise, we'll need a trivial
ubacklight-type-daemon which is system activated for this hardware (or
a polkit helper root program). The gnome-power-manager dep on HAL is
just getting embarrassing.

Richard.
