0009:err:winediag:wined3d_adapter_gl_init You are using the backbuffer for
offscreen rendering. This is unsupported, and will be removed in a future
version.

Oh... your card or driver with this card does not support framebuffer objects.
I am not sure if this is the exact reason for the black screen and exit, but
unfortunately, I am afraid this card is just generally unsupported under Wine,
at least with this OpenGL driver (I am not sure if there are other drivers
which will work with the card, but if yes, using them certainly worth trying).
Yes, I know it is DirectX 7 card which should work for DX7 on Windows, but Wine
does that through OpenGL and requires some later GL features to work.

Yet, there is a chance that some other <= DX7 games will work even under this
setup  (with MESA_EXTENSION_OVERRIDE=-GL_ARB_shading_language_100 of course).
