Back from the weekend. Yipee!
After further reading, I dumped GLDirect and modified my nwconfig.ini and nwn.ini files... now I can run NWN on my voodoo 5 without additional software/drivers, around 15-20 fps... slow but playable... so I'm not in a hurry on the gfx for a while... I'll save up for the gf4 ti4200 and grab it when I have the chance.
And now its a whole day since I started this entry. Sadly, nothing happened in the interim.
