My apologies, I went back and followed your email re pci_write_config32
step through properly, and of course you're right.  In this context this
doesn't really matter, since the pci_ops_mmconf selected by the fam10
northbridge are not invoked.  So provided we're not (inadvertently)
making config space accesses that do so, switching the mapping around
should be fairly safe.

(That said, if these accesses are not touching that address region, what
accesses are?  If none actually do, switching the mapping around
wouldn't really seem to accomplish much?  Anyway, it seems my
understanding of this particular code is less complete than I thought,
so I'll butt out of this discussion for now.)
