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]);

/*

* 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;
