That's done much earlier ... as part of PCI quirk handling.
See drivers/usb/host/pci-quirks.c ... it's not been part of
the HCDs for about three years now. I don't recall the details
right now, but letting the BIOS hang on to that hardware was
causing a lot of wierd problems that went away when we made
that change.

If a module fails to load, fix the bug in that module. :)
