Are the AppleTalk devices on a switch? This smells like a portfast problem. Enable portfast on the switch ports, and I suspect the problem will go away.
I think that what's happening is that when the newly booted AppleTalk stations send their ZIPGetNetInfo packet to find out the actual network number(s) and zone(s) for the segment, the switch is not yet forwarding their packets. So they don't get through to the router. This causes the stations to think they are on a non-routed network and to stay with their startup network number in the 65,280-65,534 range. Later the stations send other broadcasts and the router sees them and adds them to its ARP cache. As you may know already, a switch can take a couple minutes to start forwarding traffic as it works on pruning the topology into a spanning tree. New Macintoshes boot way faster than this and can be done with their initialization by the time the switch decides to forward their traffic. The solution is to configure portfast (or the set port host macro on high-end switches). These configurations cause the switch to start forwarding traffic immediately.
