What is also quite strange is that - at least for Dungeon Siege - someone wrote a test for wine 1.1.37 running on Debian Squeeze where he claims the multiplayer to work. Therefore I tested this wine version but it did not work for me on Ubuntu 10.04 (64-bit). Further testing then brought me to the same result as Jean. It is maybe also worth noting that both games use Direct Play.
Problem seems to reside before on iphlpapi.dll, not in Direct Play.
