After a bit of testing I seem to have come to a stable solutions using
my config above.

When the Dialer1 interface is shutdown the config switches to NAT over
Eth0/0.

Upon re-activation of Dialer1, new NAT will start to go via Dialer1,
but any existing connections will continue via Eth0/0 as long as
Eth0/0 is up.

So it seems to be working...

As discussed above - does it fail over when you
unplug the DSL instead - or even maybe
shut the ATM interface.

My memory is that dialers are always UP.
This is not 100% though.
