Assuming i386

>From my limited knowledge about the IRQ handling subsystems, you would
call arch/i386/irq.c:request_irq() with the appropriate flags, ie
SA_SHIRQ and any others you may require. I *think* you might also be able
to do dev->irq = irq_num and then do your request_irq() but you might
require a bit of voodoo inbetween.
