After some more testing it turned out the game can be started in fullscreen
with an older version of Wine (1.1.18), only when the following conditions are
* GLSL must be disabled (via registry entry)
* the size of the virtual desktop must be 1280x1024. It's not clear to me but
any lower (1024x768) or higher resolution (e.g. 1440x900) resulted a crash.
Later versions of Wine always crash even if GLSL is disabled.

So, if I consider Wine-1.1.18 the last working version, regression testing
resulted the following commit:

    wined3d: Deal with reserved shader constants in the backend.

    This moves the GLSL and ARB specific reserved constants out of directx.c
    the get_caps methods of the shader backends. That way the number of
    constants remains in the backend.

    GL_LIMITS({v/p}shader_constantsF) now contains the real number of constants
    advertised by GL instead of some mixture of GL info and backend
    specifics. This makes it easier for backends to decide how many constants

The patch can only be reverted cleanly on top of Wine-1.1.20, and that fixed
the issue.
