I've definitely been using the yenta_socket.o with every other distro on 
these models. I don't use any cardbus cards, just pcmcia, but the Fedora 
Core 1 kernel doesn't like this setup apparently. I don't rembemer 
having to switch to the separate pcmcia-cs drivers since back in the 
kernel 2.2 days. This 
sounds similar, but I didn't dig in far enough to find out since this 
was just one of those spur of the moment impulsive tests with a new 
distro. I doubt I'll pursue this further at the moment, but thanks for 
the observations.
