E6420 nVidia 4200M: trouble booting Sierra 10.12.2

I've all but given up on Nvidia graphics on my E6520.  Been wrestling with that for over a week now.  The best I ever got was 2 monitor support (builtin display + DVI) using nv_disable=1 and Inject Nvidia in Clover.  However, laptop was practically unusable and sleep would freeze the system.

 

I've shifted my focus to AppleIntelSNBGraphicsFB kext patching.  All I'm trying to achieve is enabling a single external monitor: VGA/DVI or HDMI).  So far no success but I'm staying optimistic.  If you make progress on that front please share.   ^_^

Please open up your own separate thread if you require support on that matter. SNB FB patches for HD3000-only models are well known and documented.
