This same BadAtom also happens for me with the open-source Radeon driver, yet does not happen with the binary driver. It looks like the problem most likely lies in the "fallback" brightness-control methods used when the xrandr backlight property is not supported. Note that fglrx supports xbacklight, but radeon does not.
