Use software vertex processing instead of mixed?

Ok. I've sent the patch to wine-patches.

The other thing which is strange is that I only get trouble about mixed 
vertex processing on Windows. On Linux CreateDevice() succeeds in 
either mode.

About that function, by the time we try software vertex processing 
we've changed AutoDepthStencilFormat. Shouldn't we try more something 
like this pseudo-code:

    for processing in HARDWARE, SOFTWARE:
        for format in D3DFMT_D24S8, D3DFMT_D16:
            if SUCCEEDED(CreateDevice()):
                return device;

I.e. based on my very limited recent experience it seems to me that the 
sticking point is more likely to be the vertex processing mode than the 
depth stencil format (I have confirmed that on my GMA950 CreateDevice() 
succeeds for the D24S8+SOFTWARE combination).

(I ordered the loop so we pick HARDWARE if at all possible as it seems 
to be the goal)
