>Description:
cpuctl mis-identifies Intel(R) Core(TM) 2 Duo and Intel(R) Core(TM) Quad CPUs 
as Intel Pentium III (Katmai).  This is apparently because these new CPUs share 
their family/model ID with the older ones.  See also the following thread:

>How-To-Repeat:
Try 'cpuctl identify 0' on a Core 2 Duo machine.
>Fix:
One possibility would be to use the CPU brand string for identification.  
Another option would be to simply report the family/model in cases of ambiguity.
