Actually, I don't think ACPI needs any extra hooks.  In the ACPI driver
you can just set up everything so that the usual PCI driver can proceed
normally.  But you could probably simplify the ACPI part if there were
some hooks into the MI code; it could also avoid code duplication between
ACPI, OF, etc.
