    $ grep name /proc/cpuinfo
    model name  : Intel(R) Core(TM)2 Duo CPU     E8400  @ 3.00GHz

Which is detailing that exact cpu vs. the class
of which it is a member.  So are you suggesting
to map all instances of processors called out
in /proc/cpuinfo into one of the three defined
models?  We can certainly do that however I was
looking for a more terse and simplified solution
at this level while deferring more ornate mapping
schemes to management tools.

Still at the user facing CLI this doesn't strike
me as the most friendly encoding of a -cpu <name>.
