What driver? rtnetlink? cardbus? tulip?

I understand that I presently cannot enable rtnetlink for a computer with
cardbus network devices, but that's hardly a long term solution, is it?

This is why I wanted someone to have a look at it. I considered it likely
that my simple/stupid patch was not correct, but the important part of my

What is the correct solution, then? Who's at fault?
