Yes. The thing I spotted was that you have 'int' (or is it 'unsigned
int') to describe a port address. I think that needs to be 'unsigned
long'. Ideally you'd have some other way of specifying a port, or of
finding out what ports there are, since PCI ports can change their
base addresses from boot to boot and PCMCIA ports don't even _have_
base addresses.
The other thing is that user-space applications can use interrupts if
they have a little bit of kernel help. Read up on ppdev if you
haven't already.
