The Diamond Viper V550 is a TNT card, not a RIVA128 card, and there's no such thing as a TNT128 chipset despite the fact that the TNT is a 128-bit chipset. I don't believe I've ever come across an AGP card or a PCI card with a chipset that supports AGP (the TNT chipset for instance) that requires an IRQ.
