Please try again with this environment variable:
MESA_EXTENSION_OVERRIDE=-GL_ARB_draw_elements_base_vertex
With that extension disabled the game runs with wine 1.3.30 and current mesa master as good as it did with wine 1.3.20 and mesa of that time. The only glitch is that every 10th grass is bright green (randomly changes which ones). Of course this is with static lighting.
