Problem is that even if we read the MMCONFIG table location from the

I've seen a lot of systems (including brand new Xeon-based servers from
IBM and HP) that output messages on boot like:
PCI: BIOS Bug: MCFG area at f000 is not E820-reserved
PCI: Not using MMCONFIG.
As I understand it, this is sort of a sanity check mechanism to make
sure the MCFG address r
