I found new driver on NVIDIA's website at the bottom of their drivers page. It appears to be non-WHQL and should support the TNT and TNT2 Ultra (only verified it works with the TNT2 Ultra). I don't know if its been posted already but I thought you might like to know since alot of people I have seen have been looking for a way to install the latest drivers for their TNT/TNT2 Ultra video cards. The text at the bottom of the downloads page reads:
"**For products not listed here use the following download."
