# of processors

[Kolbe Kegel]

I'm very interested to know why your output is so different from mine. 
Perhaps it has to do simply with the fact that you're using ppc instead 
of x86. My system has many more fields than does yours, and in fact the 
only field in common is "bogomips". Attempting to grep ^cpu on my 
machine would match "cpu MHz", "cpu family", and "cpuid level" for a 
count of 3. That is clearly not the result that we're looking for! This 
is quite an interesting discrepancy actually, you would think that there 
would be some attempt at standardization of this information. It's also 
interesting that your cpuinfo includes information on the motherboard 
and the amount of RAM in your machine. Those things seem almost 
completely unrelated to "cpu info".
