Can't you just put your ADSL router in RFC 1483 bridge mode and then 
have m0n0wall do PPPoE on its WAN interface? That's the clean way of 
getting that WAN IP address on your m0n0wall, and then you can do 
whatever you want with your /29 subnet, like using 1:1 NAT or assigning 
it to an optional interface.
