It seems to me you could use dummynet/ipfw2 to provide a stronge PREFERENCE for packets w/non-zero precedence -- the fairness aspect of dummynet queues works against your stated aim, but probabilistically you could pass all such packets ahead of others. The fairness guarantee means that, even if you had a steady stream of non-zero precedence packets, some others would be transmitted.
