Are you claiming that the USB controller IRQ line isn't routed to the
APIC? If so, I'm curious as to any evidence you can provide to that
effect.

I'd appreciate a pointer to any discussion or whatnot. URL? Or even a
suggestion for where to search? I think I've looked pretty
thoroughly...

But looking at noapic mode a bit more closely, it appears likely that I
can survive with its limitations, so thanks for the tip!
