I have the game (tribes) and have trace logs for you. The first on is +relay,+dinput,+event (which has me pressing the a key, then shuts down) and the second is +opengl,+x11drv,-dsound. DGA is disabled as it breaks my Nvidia driver when running the game.
Well, I am investigating the DInput problem... Looks strange. I may well ask you to add some more TRACEs in the code to help me understand better what happens (ie if it's blocking in Wine code or in application code).
But I would be interested on a +opengl trace too. And maybe you should try to remove all trace of glide2x.dll of your system (maybe once Tribes manages to load the glide2x it cancels OpenGL as it supposes that a system with Glide2x will work better with it than with OpenGL).
