Is there available working FreeBSD support for Ryzen 4500U based gpus?

I tried 12.1-Release first. Then 12.2-RC3. Then 13-Current from the 2020.10.22. snapshot.

The closest to anything promising was the current. In there, the amdgpu kernel modul told me to use the module parameter for experimental support. I used kenv to provide the neccesary parameter.

Then loaded the amdgpu module with kldload.

Then tried to start Xorg with the previously generated Xorg.conf.

Than I had a nice crash.

Now I use ubuntu 20.04. It has some "vesa"-level graphics. As far as I can tell, no acceleration so far:

Maybe there will be drivers on linux sooner. I can't tell. But if it's possible, I'd rather use FreeBSD (and mate) as a desktop.

The power consumption is amazingly low of this piece of hardware. So I would definitely want to use this little box for a desktop as well if possible.
