On i386 I am trying to do a similar thing and I use the following
functions:
     i386_get_ioperm()
     i386_set_ioperm()
to get access to the parallel port(s).  Then I use:
     inb()
     outb()
to do I/O.  I don't know if it's the right way to go but it works (as root
only).
You can find example in  "Priority and speed (Long...)" in the port-i386
mailing
list (June).  I have no idea for other architectures, maybe there are
similar
functions.
