Actually you should instruct routing engine to do ARP lookup if you want
to reach some IP address via ethrenet interface directly, like:
route add a.b.c.0/24 -iface fxp0 -cloning
or, for single host:
route add a.b.c.d/32 -iface fxp0 -cloning
/32 is important, it actually this enforces network route with netmask
255.255.255.255 to be added into routing table, from my practice, only
network routes can be ARP-resolved.

Probably.
But looks like you want to install interface-specific routes,
I guess it is better to put anything interface-specific in
ifconfig_<ifname>[_alias*] or /etc/start_if.<ifname>
