Sure. Here it goes... Please let me know if more editing is required.
brightness status is reported by the Apple Cinema Displays as an
'unsigned char' (u8) value, but the code used 'char' instead.
Note that he driver was developed on the PowerPC architecture,
where the two types are synonymous, which is not always the case.
Fixed that. Otherwise the driver will interpret brightness
levels > 127 as negative, and fail to load.

really appreciated. This is my very first (and tiny) contribution to
the linux kernel, even though I've been a user since the 1.2.x series,
back in '96.
