I took a look at the D3D_OK hack, and I believe the problem to be
CheckDeviceFormat in wined3d/directx.c. This function should return an error if
D3DFMT_D32 is checked for on cards which don't support 32bit depth. Currently
it just returns OK for most formats though. This code is really just a stub as
it stands, and needs to be converted to check if there are any visuals that meet
the requested format's requirements, and if there is, return D3D_OK, otherwise
D3D_NOTAVAILBLE.
To test my theory, try returning D3D_NOTAVAILABLE for the D3DFMT_D32 case
(you'll need to add it) in wined3d/directx.c in IWineD3DImpl_CheckDeviceFormat()
and see if that fixes that issue or not. This would be just another hack
though, so a real patch would still be necessary as I decribed above.
