  The comments would seem to indicate that this is only needed if you 
have a second controller.  Which leads me to wonder what if I have 3 or 
4 pdc controllers.

        for (port = 0; port <= 1; ++port) {
                ide_pci_enablebit_t *e = &(d->enablebits[port]);

                /*
                 * If this is a Promise FakeRaid controller,
                 * the 2nd controller will be marked as
                 * disabled while it is actually there and enabled
                 * by the bios for raid purposes.
                 * Skip the normal "is it enabled" test for those.
                 */
                if (((d->vendor == PCI_VENDOR_ID_PROMISE) &&
                     ((d->device == PCI_DEVICE_ID_PROMISE_20262) ||
                      (d->device == PCI_DEVICE_ID_PROMISE_20265))) &&
                    (secondpdc++==1) && (port==1))
                        goto controller_ok;
