I added these changes. If you modprobe max6650 without any parameters, the 
driver makes no changes to the chip's configuration. With one or more 
parameter, you can change whatever you like. I think this is a good solution 
because it doesn't assume there's a BIOS that does what you want.

Please test, review, comment...
