Hmmm, I see if we have tested a '590.  We don't test 10Mbps cards for
the product, and I pull out those (_really_ old) cards only when I
change driver code that is likely to have broken them.

Note that starting up a cluster nodes at 10Mbps over a shared repeater will
take a really long time.  We download about 40MB of initial system, and
just that network load might triggering a monitoring timeout.
