Before newcard, if an : IRQ was displayed on the pcicX line, the driver was using an IRQ. Now, : an IRQ is always displayed, even though the driver is using "Polling : mode"? What's the significance of the IRQ in polling mode? This just means that the BIOS assigned an interrupt to the device, but you specifically told it to use ISA interrupts and polling mode and ignore that IRQ. The PCI bus part of the system reports the interrupt that's been routed. A little confusing, I know, but hard to fix.
