Pardon my ignorance, but were there any places where the top four bits 
were actually used?  I mean, I don't believe there was a machine back 
then capable of running MULTICS and also having more than 8Gb primary 
storage.  Wouldn't it be possible to fake it by just chopping off the 
four most-significant bits and using the remaining 32?
