I'm not 100% certain Jeffrey, but there's some circumstantial 
evidence it's not a 21164PC on:

(the only page google found for me containing the string "21164-KC"), 
viz. both are listed on different lines of the table:

21164-KC 533MHz 19.9A    43.5W  67.6℃
21164-MC 600MHz 22.3A    48.5W  65.6℃

21164PC 533MHz   8.3A    18.0W  66℃      2.0V+2.5V
21164PC 600MHz   9.3A    20.0W  65℃
21164PC 666MHz  10.3A    23.0W  63.5℃

I was looking for a 21164PC chip a few months ago.  The only source I 
found was ReQuest in Holland.  I didn't proceed with the purchase in 
the end but I'll append the reply I received at the time to this
