So far I have gotten my p102-100 5GB (1080 mining card) to work with the 416.34 drivers and just adding in the entries to the nv_dispi.inf for it's dev/hw id.
Ran some fire strike and timespy, so far seems to have run into a pci-e bandwidth issue I will now troubleshoot. The card is sold as only being able to do 4x pcie but it's only at 1.1 speeds.
