Module Parameters

* init boolean
- (default 0)
- Use 'init=1' to have the driver do extra software initializations.
- The default behavior is to do the minimum initialization possible
- and depend on the BIOS to properly setup the chip. If you know you
- have a w83791d and you're having problems, try init=1 before trying
