Try "device cbb". Also make sure you have pccard. I don't think you'll need cardbus with that setup, but I'm not certain. I'm not sure about this, because I wouldn't really expect the xe driver to attach at all without pccard working, but you definitely need those in your case. Or maybe I'm way off base, since the comments in the GENERIC file would probably warn you not to delete those.
