Seems to work - though the mouse seems a bit wild, maybe it suffers from bug 6971. And sometimes the logo movie is still silent. I had to do winetricks-alpha d3dx9_36 d3dx11_43 devenum and you'll need the latest winetricks-alpha (20110222), since I added the d3dx11_43 verb just now. Easy way to download and install is winetricks-alpha -q dragonage2_demo
Work here too, in general, but I get no sound. I'm on Debian, using the Ubuntu wine 1.3.14 maverickppa1_amd64 package. Switching between OSS and ALSA, emulated and full doesn't change anything. SoundDisabled in the ini is set to 0 too. Changing the state of mmdevapi usage also doesn't change anything. I do get sound in Dragon Age: Origins. Did you do anything special to get sound, perchance?
