The problem is that kubuntu uses networkmanager.  If you've configured
an interface w/ that it doesn't define things in /etc/interfaces like
you might expect.  As a consequence, ifup/ifdown don't work.

I think the right thing to do is install cnetworkmanager (it's in the
standard repo) which provides a commandline interface to
networkmanager.  Of course, that can be a little tricky if you don't
have network access.  Maybe you can download it to a flash drive on
another machine.
