To avoid this is the reason why the bios.bin _loader_ must be part of
coreboot.
The alternative would be to pass a register write sequence description
in lbtable. But this is pretty close to a virtual machine already, so
we're almost re-inventing ACPI there. Not good.

The registers have to be changed _after_ bios.bin is copied to the E and
F segment.
