   Obviously, but that wasn't really my point.  What I'm really
after is that on ia64 you really shouldn't be assuming legacy
hardware is present and blindly poking port space and setting up
irqs based on that assumption.  Not only might it not work on
a legacy free box, it might break other things.  I think you
really need to make some attempt to determine if the hardware is
out there, and I don't see one in the rtc_init path.
