Sorry, I don´t get what you want to do.
What exactly should your file-server load-balance?
The access to the internet using both DSL routers?

That should be possible.

The basic concept is to point the default gateway of all your boxes to
your linux box and let the linux box decide where to push the traffic
along.

If you just have two normal DSL lines you will most probably not be
able to do *real* loadbalancing as your ISP would have to help you.

What you can do is to push different types of connections along the
two routers, but you have to take care the a connection (e.g. a ssh
session) is routed along the same path while active.

So you may want to set up two routing tables on your linux box (one
for each DSL router which becomes default gateway in that table) and
set up some iptables rules which decide which traffic should be routed
via which routing table (think: DSL router).

Have a look at
http://lists.netfilter.org/pipermail/netfilter/2007-June/069142.html
to get an idea about how to set something like this up (It is not an
exact example, just a similar one, but the general idea should become
clear)
