ng_fec needs a cisco at the other end (or possibly another freebsd
machine with ng_fec but I don't know that).

if your outgoing packets are going to different hosts (and not just one)
you could try:
ipfw add 1000 fwd {remote 1} ip from any to 0.0.1.0:0.0.1.0 out xmit fxp1
ipfw add 1001 fwd {remote 2} ip from any to 0.0.0.0:0.0.1.0 out xmit fxp1
where "remote 1" and "remote 2" are the gateways on each cable modem,
(or some address that will make them go to different ports)
and fxp1 is the interface tha the routing table would make them go out of
normally.
alternatively, the netgraph approach should work but I'm guessing
that you've set up something wrong..
what is your configuration?
