Which 3dfx card, the Voodoo 1/2 or the Voodoo 3/4/5?
If it is the Voodoo 1/2, you can just use Mac drivers for them with no flashing. If one of the others http://www.xlr8yourmac.com/ has some info about them under their Video section. Scroll waaaaay down.
The Voodoo 3 reminds me of the only instance I have seen a flaming video card - literally. It was a Voodoo 3 2000 AGP or PCI card (I forget which) mounted in an IBM Aptiva mini-tower. Without the cover on I hooked everything up and turned it on. I saw a light at the bottom of the machine and didn't recall seeing an LED down there. Looking at it I saw a flame coming out of the video card.
