re arrange the PCI careds on the board is the best option.
second best I think would be to go to the bios of the board and adjust
some settings, many BIOSs have the ability to tweak the IRQ settings,
where you can either set an IRQ to be reserved, or in better cases
the ability to force an IRQ upon a particular PCI slot.
but changing the order of the cards, perhaps swapping with another
PCI device(soundcard, scsi etc), may help
also be aware that some boards are designed to share IRQs between
certain slots(most common - the AGP slot, PCI slot 1 and the PCI slot
5 can share an IRQ and it can be difficult/impossible to change this
behavior).
