The virtual CPUs are more of a problem. They can't be distinguished from 
the real CPU models they are emulating other than by actually testing.

Right, hence the first-principles test.  In theory we could just execute 
the test on ALL CPUs, but I have excluded family < 6 simply because 
there is a (very) remote possibility one of them might have used that 
opcode for something completely different.

MS Virtual Server/Virtual PC.  VirtualBox seems to be a different 
problem, which seems to be related to not respecting interrupt 
boundaries properly.
