Thanks for the explanation.  I'll ask Vojtech Pavlik and Andre Hedrick
if they can suggest a better way (drivers/ide/via82cxxx.c has
Vojtech's name on it).

Actually, I have just noticed this code in drivers/ide/ide-pci.c:

                if (IDE_PCI_DEVID_EQ(d->devid, DEVID_UM8886A) ||
                    IDE_PCI_DEVID_EQ(d->devid, DEVID_UM8886BF) ||
                    IDE_PCI_DEVID_EQ(d->devid, DEVID_UM8673F)) {
                        hwif->irq = hwif->channel ? 15 : 14;
                        goto bypass_umc_dma;
                }

We may be able to get something similar added for our case(s).

Paul.
