Sorry, it's wrong for another reason.  id_iobase == 0 is the default
magic value for all devices without i/o ports (all memory mapped
devices...).  It's a stupid magic value (0 is a real port) but there
is unlikely to ever be a driver that uses port 0 directly, so it is
good enough.

The pca driver is on the motherboard but its id_iobase is only 0
because it lies - see other mail.
