On typical non-SMP motherboards, the PCI IRQs are hard-wired on the
motherboard. That is to say, INTA of slot 13 is wire-OR'd with INTB of
slot 14,

What about shared interrupts? How are they going to be treated? With the
spl leaving the arena it somehow looks feasible to run one interrupt
source on two different threads if there are two pieces of hardware
attached to the same interrupt line.
