--- Comment #7 from joaopa  ---
I think something as
    hr = IDirect3DDevice8_SetRenderState(device, D3DRS_ZENABLE, 0x55); /* test
a nonzero dummy value */
    ok(SUCCEEDED(hr), "Non zero dummy value should enable Z-buffering, hr
%#lx.\n", hr);

should be enough to prove the fix is correct. Obviously, you will have to do
the same for all the directx versions.

Surely, someone will confirm or infirm what I wrote above.
