It was a salted crypt as I recall. And the problem we ran into was that it wasn't consistent form platform to platform. Moving a board from one OS to another pretty much guaranteed your password wasn't going to work. MD5 doesn't have that issue.
I was pretty sure that someone that logs in with a crypt password was automatically converted on login to MD5. Might want to double check that to be sure, but I'm fairly certain this is true still. If that is indeed the case you can be pretty sure someone with a crypt password hasn't visited in a long while.
