I know very little about Appletalk, but I'd be surprised if this
were a problem at all.  Your machine doesn't need to receive arp
requests it sends for its own address, it already knows everything
that it could possibly tell itself.  The purpose of those requests
is most likely to detect other hosts on the network using the same
address, and the fact that it isn't getting any response is good since
it indicates that there are no address conflicts.  I think IP ARP does
the same thing for the same reason, though it only sends requests like
that when the address is first configured rather than continuously.

Your problem is likely elsewhere.  Does tcpdump show traffic from
the machines you are trying to talk to?
