From a quick look it seems at least some of those have to do with GLview limitations (e.g. complaining for ARB_fragment_program functions when ARB_vertex_program is supported and makes a lot of the same functions available) more than pointing towards actual driver issues.
I've hacked a similar check to what the GLview app does directly into the wglGetProcAddress function, and this is the result: http://pastebin.com/raw.php?i=C61vk8rH Which means about 65 functions not announced properly. If its not just my driver (346.59) it means Wine has to workaround a lot ... probably a bit too much ;)
