These driver do work to get OpenGL on Windows 2000 and using a TNT2 http://download.chip.pl/index/download_index_1240.html
Out of the list of " Detonator 3 6.31" choose the 3rd one down(3.55MB)
Once on the download page click the little gray button at the bottom right and it will download. This allows opengl on windows 2000 for a tnt2. Works like a charm for me.
