The two 8139 drivers installed with Ubuntu are 8139cp and 8139too. I'd try
those; the 8139cp first - on the guess that the 'p' stands for '+' and you
seem to have an 8139C+.
Note, I don't know anything about these modules... However, udev really
should have installed the appropriate module if there was one - which makes
me suspect neither of those might work for your card. otoh, it could be
that the card identifies itself slightly differently from similar cards, or
it could be that you have the appropriate module blacklisted somewhere
in /etc/modprobe.d/ (seems unlikely).

modprobe inserts and removes modules from the kernel. That part is pretty
generic, and I can't imagine there's much missing from the man page. It
also takes arguments to be given to the driver when inserted - and those
are _extremely_ module specific. Fortunately, very few modules need any
arguments.
