Another Wine success here, with Wine 1.0.1 on debian. I did nothing about the DirectX thing, just clicked on straight through in the installer. The launcher looks all messed up and it hung after I entered my serial. I just killed it and could start the game after that.
So far I've had two seemingly random crashes, so I'm saving frequently. Otherwise all seems fine. Sound works and graphics look good in 1680x1050 at quality 9.
