Google for IMUX, it's a standard for bonding of two ADSL lines - but
your ISP needs to support it. Then you just need a router like this:

No, in practice people generally try to do trunking of connections
below the IP level. It only really works well if you've got lots of
different types of traffic, such that you can easily build rules to
select which interface the traffic uses - eg, set up a squid proxy to
send web requests from one line, leaving the other for general
traffic. Or set up two squids in a little cluster, one on each line.

Even then the routing is a pain to setup, but the LARTC has lots of
examples of this sort of thing. You don't really need two network
cards either, they can all co-exist on the same physical interface -
though two network cards will make writing the rules simpler.
