Always using type 1 for accesses below 256 bytes looks like a very very

I know we had a lot of older kernels over the last two years that we
patched like that (we needed MMCONFIG for our own device development
purposes, but we also needed our machines to boot and discover all
devices reliably). Recent kernels works fine out of the box on all
hardware we have, but all this sometimes tricky and apparently endless
work (in big part because of buggy BIOSes) about MMCONFIG would probably
become relatively easy by limiting the aim to have MMCONFIG work when it
is required (for cfg-space accesses >= 256).

Hmmm... I think I like this solution.
It may be easier to implement than the solution I posted.
Also, this solution also would allow us to remove the unreachable_devices()
routine and bitmap.
Does anybody see a down side to this?
