Hi Jacobt,
I guess I found the solution to your networking problem.
It looks as if the Davicom Tulip driver from Suse 10 is a little buggy,
take a look at this:
https://bugzilla.novell.com/show_bug.cgi?id=121853
I suggest you try to use the dmfe driver instead of tulip,
the article says you are able to do this by changing the module manually in /etc/sysconfig/hardware/.
I have a very similar problem with the same card, I will try this possible solution when
I get home from work today.
Let me know if this works for you,
Have a lot of fun,
Stefan
