I'm still trying to find complete information about the IO APIC, but
I believe it two IO port ranges (at least) along with some memory
locations all for the same device. The IO ports are to mimic a simpler
interrupt controller which would be formed from two simpler cascaded
devices. I don't think the way PIO devices are set up currently will
allow listening on more than one range of addresses since they have a
start and size parameter and that's it. This isn't a critical issue now
since I'm just putting IsaFake devices in there now as placeholders, but
at some point the IO APIC will have to exist and it will have to listen
to more than one address range.
