"sane" or "correct"?

Uhh, are you _NUTS_?  Or if you don't care, just set them to 1, or 47.

Uhm.  This isn't a constant.  Is '2' good enough?

sysctl_byname on hw.machine will tell you sys.

There's a global cpu_class (in the kernel) which is set for this.
sysctl_byname on hw.model can be used to obtain it too.

Parse the results of sysctl_byname on kern.osrelease / kern.osrevision 
for this.

Care to explain the context?  It might make guessing the "right" answers
a little easier 8)
