OOI what is the (estimated) probability of such an RMRR existing which
doesn't already conflict with the real host BIOS?
Host BIOSes are generally large compared to the guest BIOS, but with the
amount of decompression and relocation etc they do I don't know how much
of them generally remains in the <1MB region.
