That looks good, though it doesn't seem to be remotely related to the isa
code.  I wouldn't have much objection to using that for the upc, though
the interrupt stuff would need to be abstracted, and I'd like to avoid
bus_space_map if I can (or at least move it to the parent and pass down a
bus_space_handle_t to the children).
