I don't think so. For two reasons:
a) ia64 maps the "iobase" address to user space
b) the ia64 method is fixed for the architecture on how
to generate "legacy" IO port cycles (using iobase).
parisc has two different methods (dino vs elroy) and dino only
supports poking the PCI HBA to generate IO Port cycles.
Or am I over looking something?
