RS780 function ProgK8TempMmioBase is setting a reserved
bit in the AMD processor 'MMIO Limit Address Register'.
I suspect it is because of a typo where 0x80 was entered
as 0x8. If 0x80 is used, then the strap configuration
register accesses become non-posted, which is how the
Shiner reference BIOS does it.
