Er, that would be pci_get_legacy_ide_irq(), which is what I _have_ used.

As I said, the Maple board is the _only_ user, across all architectures
and all PowerPC platforms, of pci_get_legacy_ide_irq(). And the AMD74xx
driver is the only driver which calls it -- for Maple. Hence the
suggestion that perhaps there's a better way to do it.
