Well, I could do that, but I'd rather write a complete driver with all the
regular interfaces... (open, close, ioctl, and a specific major/minor in
the kernel, I'm going to add other chips to this driver eventually) The
way you are suggesting just opens /dev/io and uses inb and outb to do some
hacking around I believe.
