My patch to support the 574B (in -CURRENT, not PAO) relegates that message to bootverbose only. > All network traffic seems extreamly slow, 15 seconds to ping a host > (and lots of lost packets).

If I'm not mistaken, this is indicative of a bogus interrupt setting (the card can't signal the computer it has packets, and they pile up waiting for the computer to just 'notice'). Look for conflicts or other issues. Fire up "systat", look for your card's IRQ, and then start a ping -f or something and see if you get a proportional rise in interrupt rate. A flood ping on my system causes 1500 or more interrupts/sec on the card's IRQ (10).
