Conceivably this is useful if the IO hub does not support MMCONFIG
accesses. The AMD 8111 does not, as far as I can see. At least I
have an Opteron system where MMCONFIG is not supported, and I assume
it's because the 8111 doesn't provide it. I don't know if this is
going to be a realistic scenario for Barcelona systems.
