Does PCI for IA64 architecture require a different kind of PCI card or just a different kind of a driver?

I have a machine that is IA64 and it has a spot for PCI cards in it. I was wondering if the PCI cards in it can be just regular PCI cards, or if they have to be PCI cards that were built specifically to work with an IA64 architecture?
