To enable the support for older cards, there has to be two changes made.
I've to check what is needed for the kernel:

CONFIG_DRM_AMDGPU_CIK=Y

Following kernel parameter needs then to be added:

amdgpu.exp_hw_support=1

The affected PCI IDs are 0x6900, 0x6901, 0x6902, 0x6903, and 0x6907 for
the Topaz/Iceland GPUs that are marked as experimental.

Seems they are in the list I've automatically generated by MHWD scripts.
Now how to support it proper I've to check ...
