Probably because the Airport supports only 10BaseT and not 100BaseT, and
when you force one end of the interface (your Tulip card in this case), 
the other end of the link needs to be in the same "forced" state for the
two ends to be able to communicate because forcing media generally dis-
ables autonegotiation.
