Yeah, that's pretty relevant.  What's happening is that dhclient3 (the
DHCP client on Dapper) is broadcasting a DHCP discovery request over and
over.  It's not successfully communicating with any DHCP servers.  Since
your laptop seems to, there is no problem with the usual suspects --
network cable, switch/hub, etc.  The interval is the just the nth
attempt to broadcast.

Which leads us to  a problem with the NIC

First off, something that puzzles me is that I see conflicting text
here.  In the lines quoted above, you are having trouble getting a
DHCP.  In the lines above that where you copy the ping results, though,
you show that you have an address, specifically

Not sure why that is.  Did you assign one manually?

Anyway, what do the results of an lsmod look like?
