To avoid this is the reason why the bios.bin _loader_ must be part of 

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.
