Dave brought up a couple of good points:
  - there's an early driver call, GET_REQUIRED_HW_INTERFACES, that
    could be used to indicate that I/O space isn't needed (saw this but
    forgot about it when I wrote the mail); it means messing with some
    early driver code, but that should be ok
  - a new KMS bus type might be a good idea, allowing KMS aware drivers
    to be probed early
