What happens when you use the FULL ACPI support? I suspect that you really
do want the interpreter, in order to evaluate _PRTs properly.

ISTR that the reason you are thinking that ACPI only is programming some of
the ioapic entries is because whatever is printing them is looking at the
mp_irqs array. Which is MPS specific. So ACPI doesn't bother filling it all
in. :)

Is that a bug? Should ACPI fill it in completely, or maybe not at all? Don't
know. But it is strictly unnecessary.
