I don't think so. You can follow Chad Leigh's advice and ping a router
on your ISP. Figure out where your packets through ISP1 are routed (try
traceroute) and then add a static route through ethernet1 to that
router. You can do similar for ISP2. Then a ping of either router will
always try to go through the network card appropriate to that ISP.
