Dunno.
but one could replace the call to /usr/lib/heartbeat/send_arp
in IPaddr2 with calls to /usr/bin/arping,
where arping come from the package called (in debian) iputils-arping.

heartbeat send_arp:
send_arp -i $interval_ms -r $repeat_count -p $some_pid_file $DEVICE $IP ${MAC:-auto} not_used not_used

iputils-arping:
(
arping -U -b -c $repeat_count -w $repeat_count -I $DEVICE -s $IP $IP &
arping -A -b -c $repeat_count -w $repeat_count -I $DEVICE -s $IP $IP &
wait
)

should be almost functionally equivalent...
