I have devices which uses multiple IO port ranges on the ISA bus (i.e. they
use 32 ports regions at three places in IO space). The current driver for
this card claims to use the whole range between min. and max. port address,
but of course that's simply wrong. With the proposed sheme this could be
fixed (and the driver turned over to bus.h).
