I believe what's missing at this point is a mmiotrace of the NVIDIA driver to make sure that there's nothing different about this GPU. If you can make one (see https://wiki.ubuntu.com/X/MMIOTracing for a guide - should end up ~100MB uncompressed), please send a compressed one to mmio.dumps@gmail.com or make available some other way.

This new graphics card was failing to initialize with nouveau due to an "unknown chipset" error.

Copy the GP106 configuration and rename for GP107/NV137. We don't know for certain that this is fully correct, but brief desktop testing suggests this is working fine.
