Hmm. Not too sure about what deleting resolv.conf
would do in this case, but I guess it's worth a try to
rename it... 

What gets me is that 0 packets were sent, there has to
be some meaning for that. Usually when you start
pinging, it sends them but you just don't get anything
back. I think this is probably the avenue you need to
follow. Can you ping your ethernet interface using the
IP?

Any nutty entries in your /etc/hosts file or
something?
