Hmmm... Can you try running xvidtune? That application uses the XFree86 Video Mode Extension. It seems to work for me over a remote connection, but it might be failing in your case because the graphics hardware on server and client are mismatched.
If that application fails in the same way, then you might be out of luck. The only other thing I could think of would be trying to run the game in a windowed mode rather than full screen mode, if it offers such an option. Perhaps it won't try to use the video mode extension if it's not running full screen.
