I don't think ARP is the right solution for this problem.  What you have
is NBMA (non-broadcast multiple-access) medium and arp just isn't

All you really need to do is modify your if_output routine for the device
to grad the address out of the route.  If there is no route (or address in
the route), return EHOSTUNREACH.

To populate your cache, simply do:

route add rn0:1:2:3:4:5:6:7:8 -interface

(the driver can convert the 1 to 0x31 etc.)
