I have a P65_P67RGRERA with an nVidia GTX 970m. I too have "kind of" got
it working by:

1. Installing the 4.6 kernel.
2. Installing the proprietary nVidia 364 driver.
3. sudo prime-select intel
4. Reboot, go in to the BIOS, and select "MSHYBRID" for the Graphics option.
5. Save BIOS changes and exit the BIOS settings (save and exit).
6. Unload the nVidia modules: sudo rmmod nvidia_drm nvidia_modeset nvidia_uvm nvidia
7. Cut power to the nVidia GPU: tee /proc/acpi/bbswitch <<<OFF
8. Make sure the nVidia GPU is turned off: cat /proc/acpi/bbswitch

By using the above, my battery life doubles (I'm getting around 4 hours
30 minutes).

Unfortunately, while the above will reduce idle power consumption from
around 25-30 Watts to around 12-15 Watts, certain commands will cause a
kernel freeze (such as lshw or lspci).
