Firstly, RFC 3217 doesn't explicitly say that the test vectors are

After reading and re-reading, I do not see how you can say that the 
test vectors are generated using 40 effective key bits. Where does 
that show up in the RFC?

It *doesn't* say that in the RFC, which is *exactly* what I am
complaining about.

I discovered it myself by trial-and-error, and to be honest, it took me
a couple of days, because there were a lot of other variables I checked
first (such as endianess etc)
