That driver would prob not be used on systems which does not support 
PIO, and so could have a HAS_IOPORT dependency. But it is not strictly 
necessary.

Anyway, it would be good to have an idea of how much ifdeffery is 
required in drivers.

That driver would prob not be used on systems which does not support 
PIO, and so could have a HAS_IOPORT dependency. But it is not strictly 
necessary.

Anyway, it would be good to have an idea of how much ifdeffery is 
required in drivers.
