   In ring 3, you'll seg fault.   
      
   In ring 0, you should get all ones (IIRC). The transaction goes down the ISA   
   bus and times out.   
      
   My knowledge is pretty dated. It's possible chipsets that have dropped support   
   for ISA will behave differently.   
      
   Those addresses should resolve to uncacheable, so there will be a pretty hefty   
   performance penalty in any case.
