Does dhclient.conf provide enough configurability for this?  For
example (syntax might be slightly wrong, but you get the idea):

    supersede routers; # I know better than the DHCP server
    prepend routers;   # Try my router first.
    append routers;    # Try my router last.

Ideally, they should all be used in some sort of load sharing or
failover scheme.  But, while we don't have that, I think the first one
should win.
