Blacklist it, and use the acer-wmi backlight interface instead. Note that the KAV80 is somewhat unique in that it is the only Acer model where we fall back to acer-wmi after blacklisting, rather then using the native (e.g. intel) backlight driver. This is done because there is no native backlight interface on this model.
