While I fully expect this is a badly done troll there is a very tiny chance its real and they are just buying cheap products and rebranding with 3DFX with the hopes of making easy money. Some generic cheap Android phone with a 3DFX label.
The 3DFX VSA-100 chips area easy to make and cheap to buy in bulk. People have brought them and recreated a 3DFX Voodoo 6000 for PCI slots. Compared to making an entirely new GPU this is relatively easy and they could just be re-creating the never released 6000 to sell. In which case the Voodoo6 PCI reference makes sense and they can just re use the same BIOSes, same drivers, same bugs as the Voodoo 5. Although more likely its one poorly thought out troll, I am just saying its more feasible then it looks like at first glance. This would also explain the 3 month turn around.
I guess the audience will largerly overlap with that of the freedom phone then...
