Another product (not free but MUCH cheaper than MC/SG) is Auto Port Aggregation (APA). It will do exactly what you want and actually increase bandwith when both ports are fully functional as well as provide failover. It only works with certain ehternet switches so check the hardware matrix.

I didn't know about the switches, which is good to know. ALSO, it works only with certain ethernet cards, so do checke them out, too.

if the single IP address is the binding point for you, you can use a load balancer of some sort. If you have an unused hardware load balancer like a Cisco brand one, you can use this kind of device, or you can build one from a fast x86 (PC family) box and 2 high speed NICs running a stripped down and specialized linux distribution.

I must agree, APA is the first solution that comes to mind when you mention 2 interfaces with the same IP address, but sometimes, configuration and troubleshoorting of APA is overwhelmin. So, my suggestion is another alternative.
