I agree, but the puc-style `here we have a long list of cards that we
know about' isn't very pretty either. Guessing that a random serial
card is based on something that is 16x50 compatible is probably not
too far from the truth (and this is what puc does too). A negative
match might be more useful (cards that we know to be non-functional).

We should get this information from CIS.
