Yes, that is my own conclusion regarding drm-legacy-kmod-g20180921 which 
is based on a recent CURRNT source - and by the way can not be used on 
STABLE-11.

But the more fundamental problem is that the drm-legacy-kmod ports do 
not contain any firmware, and are unable to use the firmwares of the 
gpu-firmware-kmod port (absence or renaming - I do not know)
