Evap cannister question

1999 Boxster. I got a P0446 code. One of the possibilities is a bad EVAP cannister. I'm trying to determine if my car is ORVR or not. Looking at my build codes under the hood, I have neither M660 or M664. Big difference in cannister costs. Anyone have an idea on where I can turn?
Oh, and regarding the P0446, other things to look at other than the cannister?
