You do not need a virtual IP address (such as an HSRP or VRRP setup). You just need equal cost paths from the ISP to you. To achieve this you will need to route an address range from your ISP to your network. It can be your address space, a small piece of ISP provided space, or even a chunk of private space. Just as long as it's routed from the ISP to you via the DSL tails. The ISP just needs to see equal cost paths to your prefix via BOTH your DSL tails. That way they will use both. There are several ways to do this (inc running eBGP or OSPF to them from your equipment). Have a chat with your ISP to see what options they would consider.
