[RESOLVED] OpenGL and TNT2 Ultra

I Recently installed a Guillemot Xentor 32 in my system. The card performs well but any application utilizing opengl ie Kingpin, Q2, etc refuses to run stating no hardware device found. I installed the card by the book, removing all (I believe) traces of the voodoo2 cards that were there. I used the 3dfx file delv.inf to remove anything left in the registry after I did it manually. I'm not a newbie but I'm feeling pretty stupid.
Can anyone help?
