 One difference between the 1.6 bootcode and the current copy is that
 prot_to_real used to do an immediate ljmp having just written to the
 code to patch the instruction.  I changed it to do an indirect longjump.
 
 I don't think anyone has tried reverting that change.
 (Nor the other subtle changes required to get the correct address mode
 and bound bits set in the segment descriptor - IIRC especially SS)
