Hmm.. what kernel are you running..?  I do have another PCMCIA nic from
Netgear .. if I can locate it  .. 16 bit I think .. and I could give
that a try.

The problem I have with switching back and forth just for a quick test
is that this a cable-modem setup and my ISP check the nic's mac address
to make sure you are legit .. so if you switch to a different nic you
have to call them and say you bought a new computer or something ..
otherwise they won't let you through ..
