Just a guess, but try disabling GL_ATI_separate_stencil and GL_ATI_envmap_bumpmap by commenting them out at line 57 and 60 of dlls/wined3d/directx.c
Disabling those 2 extensions allowed me to run a successful dxdiag 3D test.
Gentoo users should be able to do that with ease since it only requires to add a patch to a local ebuild.
This patch is not necessary for me to run wine 3D stuff successfully on my 2 32-bit systems, so I won't be able to confirm it fixes anything on 32bit... :-D
Could a 32bit user test that ?
