It seems at least Civilization III: Complete (Steam version) tries to make some use of it. Wine prints the following error when the game is loading to the main menu. This is with Wine compiled without OSMesa support:
>err:dib:dibdrv_wine_get_wgl_driver OSMesa not compiled in, no OpenGL bitmap support

I tried the Fedora version of the patch, but it didn't make it better. The error message changed to
>err:dib:init_opengl Failed to load OSMesa: /lib/libOSMesa.so.8: undefined symbol: _glapi_Dispatch
when Wine was compiled with that patch.
