Where's this supposed to get hooked from? In the driver sometime long after pcibios_init? This could get really ugly, since we might have to re-do pci_set_bus_ranges.
I would much rather see this sort of thing somehow handled during quirks fixup header, as then we don't have to duplicate work.

I disagree. At issue is that those arguments are to protect allocation on top of "magic" legacy i/o and mem regions. Specific devices such as IDE *will* be allocating out of that region.
