cgd 04046c6dd7 add code to cope with multiple ports per BAR, as are found, for instance,
on the 8 port card Simon Gerraty has.  In general, cards which have
this lots of ports also have a separate interrupt status register, but
this change is just to talk to the various ports independently.  It works,
but it's not optimal.  (XXX still need a good name for the card in the
comments, and to update the manual page.)
