Can you attempt to build run it with this in your make.conf:
WITH_DEBUG_PORTS=x11/nvidia-driver

Just as a sanity check please make sure you are building the port
against the exact kernel sources that will be booted with the above.

If there's a chance the shim code is involved we have a shot at doing
something or finding a better lead.  Otherwise your best bet is to
report it to nvidia support forum.  There is a report of a successful
outcome on a Kepler architecture card so it seems you are encountering
a more specific bug than HW generation and I'm not sure what to expect
yet.
