Just want to post my findings on this:

The game runs great under linux via wine 1.5

so far i've not had any issues

running on 64bit kubuntu 12.10, liquorix kernel 3.7 and latest ati/amd drivers

Totally out of luck here with Wine 1.5.6 and the r200 DRI driver: the loading screen is displayed but nothing after that. Audio works; it sounds like there is a video intro that you can quit with esc but neither the video nor the screen after that are rendered. You and the Wine application database report success, so I guess I am hit by some rare combination of Wine and driver bugs, possibly also game bugs. I have also tried setting DirectDrawRenderer to gdi but then the game crashes on startup, which suggests that the DRI driver is not alone to blame.

Update: finally got it to work. The solution was to set Direct3D\OffscreenRenderingMode to backbuffer (with regedit).
