BTW in answer to the question, "Why would the change of kernel affect
the behavior of dumb network devices?"  I had considered the
possibility that the device initialization for the NICs, as specified
in /etc/modules.conf, was not being done the same in the new kernel.
It had also been suggested that the new kernel might have discovered
the devices in a different order than the old kernel did.
