	Thanks, I will use some of this text if I can, and be sure to give
	Matt credit.  If that was too much detail, is there a place for the
	detail? 

	Next week I am going to attempt to determine the cache size via the
	cpuid instruction, and export some of the calculation parameters via
	sysctl (to help with some simulations that we are going to be doing).
	Given that nobody has done this yet, am I missing something that will
	bite me?  The intel IA32 manuals seem to indicate that most of the
	(intel) cpu's in use today should support cpuid 2 lookup?

	Thanks.

	Chad
