I can appreciate the concern of wanting to get this
as "correct" as possible.  But ultimately we just
need three unique tags which ideally have some relation
to their associated architectures.  The diatribes
available from /proc/cpuinfo while generally accurate
don't really offer any more of a clue to the model
group, and in their unmodified form are rather unwieldy
as command line flags.

Here is a pointer to a more detailed version:

We probably should also add an option to dump out the
full set of qemu-side cpuid flags for the benefit of
users and upper level tools.
