If we can't find a free interrupt, we can always connect it to interrupt 5; that will reduce the number of pci interrupts to two. But we can implement apic mode and use lines 16-23 (if we add another ioapic, 16-47). -- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain.
