What network card? Multi-cards? Is the card detected?

Around 2.5.71 the 3c509 init/detect changed such that the
second card is not detected.  Will get the badness when attempting
to bring up ppp/ppoe on a non-existent card.  

The 3c509 multi card breakage still exists at test10. I replace the
driver with 2.5.7x version to get my pppoe.
