Updating the gpu-firmware-kmod meta-port has fixed the issue. Loading amdgpu.ko
from drm-61-kmod-6.1.69_2 does no longer panic the kernel.

kldstat now reports the following about graphics related modules:

We were able to start a very bare-bones X session; getting that running
properly is a different story. ;-)
