Hi!

You'll need the drivers from Linux 5.12. They are not available in the 
Ports tree as of this writing. You need to compile them from the 
following Git repository:
https://github.com/freebsd/drm-kmod

The `amdgpu` kernel module you currently have loaded successfully but it 
didn't attach to your device (it doesn't know about it). That's why you 
don't get any /dev/dri/card0 and that the X.Org server "cannot run in 
frame buffer mode".
