Roland, ARP is an Ethernet and Token Ring protocol which is required in order to do ARP over ethernet. Heartbeat's IPaddr script (via the send_arp tool) can send RFC1042 ARP packets over any link that supports the IEEE 802.2 data layer, which includes all kinds of Ethernet (including wireless ethernet) and token ring networks.
You didn't say anything about what kind of "special device" you have, but at the very least if it is a point-to-point interface, then no gratuitous arp is required. My heartbeat configuration has the cluster IP address attached to a loopback interface, which obviously has no need for ARP packets. If you provide more detail we may be able to provide a more useful answer.
