Hi Klipp,
I don't know if this applies with PCI cards but the old multifunction cards used to have jumpers that set the IRQs for the various ports. If I remember correctly the OS/2 drivers that support the the printer ports require the IRQ to be below IRQ15 and your PCI output shows the assigned IRQ to be 22.
How you get round this I don't know but I think it should be possible. The windows inf file might give a clue as to how windows does it or you might have to reserve an IRQ in the bios for the card.
