You can use the iproute2 utilities to do this.  Note: there seems to be
bug when using both NAT and load balanced default routes which I can into
(and which was alluded to the Netfilter list).  Not sure if there is a fix
yet.

I currently have 2 links operating in a fail-over configuration with
certain specific routes going out the secondary (such as a web proxy-cache
to act as a parent to a local proxy-cache).  A script running locally on
the firewall rationalises routing if one of the links drops unexpectedly.

Works well enough until I get back to trying load balanced default routes
again.
