I wouldn't worry too much about it. My P5KPL-CM mobo is rev. 2.01G but CPU-Z shows it as rev. 10, so it doesn't seem to be very good at that. As long as everything else looks fine, you should be good.
Well they never made a Rev. 00 anyway. Just 1.0 and 2.0. If you want to make sure you have the right one. Rev. 2.0 has the Southbridge 710 with a Silver heatsink on it. Rev. 1.0 has a 700 Southbridge with a blue heatsink.
