unequal cost load balancing can be achieved with MPLS TE. You can create two or more tunnels to the same destination router, which will show up in your routing table. Each tunnel will get an IGP metric of the shortest possible path to the destination regardless of it's real path. CEF will do the load balancing based on the configurable reserved tunnel bandwidth.
For details regarding MPLS TE have a look at f.e. "Cisco IOS Multiprotocol Label Switching Configuration Guide, Release 12.4"
