All you really care about is the "legacy" I/O spaces here, this isn't
tied to PCI specifically at all, right?
So why not just have a OLD_STYLE_IO config option or something like
that, to show that it's the i/o functions we care about here, not PCI at
all?
And maybe not call it "old" or "legacy" as time constantly goes forward,
just describe it as it is, "DIRECT_IO"?
thanks,
