Main menu works flawlessly, as does the pre-game launcher. Campaign map works, though slowly, and in-game battles are working stupendously. The Third Age mod is also working great, as are all the Medieval 2 campaigns.
What does not
Campaign map was very slow for me, and may try your patience. Transitions between loading screens was slow but picked up immediately after the transition finished. Loading times compared to native windows version are slightly longer.
What was not tested
Multiplayer and extensive playing (extensive being 50+ turns).
As Maquis mentioned, dotnet35 (use winetricks) is necessary to run the game's launcher, which is in turn used to select which campaign you wish to play. If you've gotten past the launcher but are having trouble getting the actual game working, try installing d3dx9 with winetricks. All in all, a solid Gold rating, as the only dll override needed was dotnet35.
