I doubt there is any way to do this sanely in the kernel. Usually you
would need to move either the PCI hole (which is hard or impossible) or all
RAM beyond it (potentially breaking SMM assumptions and causing other problems).

Normally the memory controllers don't have a way to just remap pieces because
that would need much hardware in critical paths.

The only half way sane way to attack this without vendor support
would be LinuxBIOS imho.
