NOrmally it would be VRRP/HSRP with interface tracking, but since you said that it's Ethernet than this is not possible unless you have a method to track end to end link condition (something like frame-relay end to end keepalive.
Perhaps a tunnel might do the job.. Not sure never tried this.. basically, create a point to point tunnel (GRE will do) with static route pointing to the other end specific IP address.
After that you create another static route pointing to the tunnel interface for the routing between the two site (the first static route is only to get the tunnel up and running since there is no routing protocol). Never tried this, so you have to try it.
THe best solution of course is the one that is currently not possible... which is routing protocol.. :)
Cheers,

Hi All,
I have got a client who has a branch office with two different physical links back to HQ. Both links are over a shared service provider metropolitan area network. Both links are delivered via Ethernet interfaces to the branch router (ISR 2811).
The client does not use a dynamic routing protocol
Static routes are in use
Client requires a solution that will provide dynamic failover between the primary and secondary links when the primary is not available. The above caveats cannot be changed for now.
Please can anyone help with a solution, considering the peculiarities of Ethernet interfaces not detecting the remote end been down as long as the local interface is seen as up/up when plugged into a switch port.
Regards,
Bola
