Sounds a little familiar to what I had to go through to get Deb working on my laptop...

Check out [link|http://www.mikevitale.com/1905s303.html|this page] to and see if it helps. Best I can do for right now; I'm on my way home. Will check back tomorrow morning. G'luck. (NOTE: I don't have the same ethernet card as you do, but maybe something I mention in there will help y'out...)
