Might as well try this updated version:

I discovered that there's a nascent standard for CPUID behavior under 
hypervisors like VMWare, so I implemented a check for it.

Thanks again for the testing. The more CPUs and environments, the better.

I'm also looking for architectural reference manuals for as many x86 
CPUs as I can find, or at least documentation on what they return with 
their CPUID instructions. I have all the Intel and AMD documents, but 
the others are a challenge. I can't find a single such manual at the Via 
site, for example.
