All is
OK now with King Beowolf's suggestion "-net nic,model=pcnet -net user"

It seems changing the network interface card was most likely triggering
the re-certification requirement as it counts for 3 votes.
There must have been a change in the default network interface card
between versions 1.2.0 and 1.4.0, Anyway I will now be careful to define
the nic on the cmdline which starts qemu.
thanks for the additional info.
