At the moment wine always set the PFD_GENERIC_ACCELERATED flag in X11DRV_DescribePixelFormat. SeriousSam uses this flag to determine if the pixelformat is hardware accelerated. If the flag is set it is interpreted as _no_ hardware acceleration available.
Well, the best way to check this would be to run a test case on a Windows box with OpenGL installed and accelerated.
Then create the most standard pixel format (ie double buffer + depth buffer) and see what the pixel format is. If it does not fill GENERIC_ACCELERATED, we should do the same in Wine.
You can provide a similar behavior with opengl:

<snip> GLX_CONFIG_CAVEAT This attribute defines any problems that the GLX FBConfig may have:
GLX_NONE No caveats GLX_SLOW_CONFIG A drawable with this configuration may run at reduced performance. GLX_NON_CONFORMANT_CONFIG A drawable with this configuration will not pass the required OpenGL conformance tests. <snip>
as example you can see wglGetPixelFormatAttribivARB implementation in dlls/opengl/wgl_ext.c :)
But you must test what windows provide and on which configs
