That explains why it's not recognized, so indeed you are hitting the fallback
path. The old fallback code was able to recognize your card as capable of at
least DX10 based on the presence of EXT_GPU_SHADER4, but the new code that uses
the shader capabilities no longer has access to the list of OpenGL extensions.

And since the problem will be solved the right way by using core contexts (work
in progress) I doubt anybody will be willing to workaround this cornercase
until then.

The only solution for now would be to add the renderer string for your card to
cards_amd_binary array in dlls/wined3d/directx.c It should like:
    {"Turks",                     CARD_AMD_RADEON_HD6600},
