Dan: I just verified that I get an IRQ storm when I plug a 3.3-volt based SMC EPIC/100 network card into the PCI slot of the Au1500. Before I bring the interface up, I notice that the driver tries to allocate IRQ 1 (INTA). This is the same IRQ that the ill-fated CardBus bridge attempts to use. ;) As soon as I bring the SMC interface up using ifconfig (and have the interface plugged into an active Ethernet network), the IRQ storm ensues. I'll try Hartvig's patch, look over the irq.c levels, and see how everything fares. Thanks all!
