It does that check as that is the correct check to do. If the device is in native mode with no assigned IRQ we must poll, we cannot assume that legacy interrupts are in use. > Change ata_pci_sff_activate_host() to try the legacy IRQ > numbers (which works correctly) when the dev->irq has not > been set.

If they have no mapped interrupt and are not in legacy mode then they have no interrupt we can use and we should poll. Your assumption that if no IRQ is assigned we should use the legacy interrupts is incorrect for PC class systems. Can you not correct this with a PCI quirk handler for your board instead ?
