Yeah, its pretty much the same, although it says IO-APIC instead of XT-PIC.

If I don't use pci=noacpi, I get the problem I'm describing (obviously), with
IRQs 21 etc mentioned.
If I use pci=noacpi, it also says IO-APIC, but it only has 16 IRQs total.

(I can't remember the _exact_ word it uses offhand.. something like
IO-APIC-edge I think)
