Thanks for digging into this. The actual problem seems to be 
NV_DRM_DRM_DEVICE_H_PRESENT not being defined despite of the header 
actually existing ... I missed to backport the check for 
drm/drm_device.h which was introduced much earlier than 470.63.01 (where 
I took the drm_device_has_pdev patch from), could have been 390.138, but 
that did not exist in the 340xx series, yet.
