I'm not %100 about that specific feature, but there is quite a bit of 
work happening with the drm-next-kmod port/pkg.  currently it only works 
on CURRENT systems, but it is pretty closely in sync with the Linux's 
Intel GPU support.  There is also work happening on the radeonGPU front 
in this package to bring it more closely in sync with what Linux already 
supports but we need more testers on that end so I can't speak 
specifically if it addresses the issue you are running into.

so, if you are OK running CURRENT on your system you can simply install 
this package:

$ sudo pkg install drm-next-kmod

And after installing X and so forth this hopefully will just work. On my 
Intel systems I allow Xorg to autodetect its configuration which results 
in the "modesetting" graphics driver being used which has support for 
hardware acceleration.

I know this doesn't answer your specific question but hopefully it's 
helpful.
