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.
hm as far as I had understand that there is no direct way to determine whether hardware acceleration is used or not.The only way is to do it indirectly via DescribePixelFormat(). So I can't really use DescribePixelFormat at the same time to test whether the GENERIC_ACCELERATED flag stands for hardware acceleration or not. It's kind of chicken and egg problem ;)
However I will just assume that ATI ships its opengl drivers with full hardware acceleration support.Attached is the output from wglinfo[1]. The column 'geac' shows the PFD_GENERIC_ACCELERATED flag.As you can see it is never set. So from this I would conclude that PFD_GENERIC_ACCELERATED should not be set.(at least not unconditionally)

[1] You can get wglinfo from here: http://www.cg.tuwien.ac.at/~wimmer/wglinfo/
Note that the equivalent does not really exist in GLX (except maybe between the direct / indirect rendering pathes but this is not the same distinction than in Windows).
