IA64 boxes only have PCI IDE devices, so there's no need to blindly poke

hmmmmmmmmm.  Are you POSITIVE that the legacy IDE ports are never enabled?

In modern Intel chipsets, this still occurs with e.g. combined mode.

I don't know about combined mode.  If the legacy IDE ports are
enabled, shouldn't they be described via ACPI, and hence usable
via the ide_pnp - PNPACPI - ACPI path?
No idea...  that's more for platform IA64 people to answer :/
