Well a few more than I remembered, but here's my notes; I think this
works (add the iproute2 package if you don't have it), GATEWAY0 is
used on a 6:1 ratio with GATEWAY1 (or vice versa?)


GATEWAY0=216.254.97.1
GATEWAY1=65.185.37.22
NIC0=216.254.97.15
NIC1=65.185.37.21
route del default
ip route add 0.0.0.0/0 via $GATEWAY0 table E0
ip route add 0.0.0.0/0 via $GATEWAY1 table E1
ip rule add from $NIC0 table E0
ip rule add from $NIC1 table E1
ip route add default scope global \
        nexthop via $GATEWAY0 weight 6 \
        nexthop via $GATEWAY1 weight 1
ip route flush cache


Not sure what happens if a link fails and I wonder if it would work with
one physical interface...
