For both of this you want to use the bus_space access method instead of
allocating port and do inb/outb by yourselve.
Have a look at the bus_space(9) manual page, and some drivers of sys/dev/isa
(boca.c for example).
This way your driver will work with minimal changes if you ever have the same
chip on another bus, or this board in a non-i386 machine.
