Now that I am not racing against a release deadline, this is a
possibility. It probably means falling through to the "fake an EOI for
line level interrupt code", as the Status bit is RO in the IO-APIC (The
IRR bit is RW but both need updating)
Does anyone know which revision of the IO-APIC was the first with an EOI
If not, I think I have some document trawling to do.
