We did together some patch which makes finally a MMCONFIG workable in
linux out of the box. There were two problems. First was that the
mmconfig ACPI structure was empty because of cut and paste (PCI ID of
K8M890 is different).
Second problem is now nicely solvable by add_region. Linux expects that
the mmconfig region is found as reserved memory. Otherwise it does not
trust it.
