I don't know, but let's make sure we support that easily (if
not right away).
I already made sure there's a clear separation between IRQ and
vector, so it should be possible to map the {PIC,IRQ} pair to
an unique vector. The Heathrow PIC driver needs to maintain its
own IRQ->vector mapping then, but that's trivial (we still have
IRQ==vector to avoid such a mapping).
FYI,
