It seems like this does not help.

and changed nothing about the modules and their ordering. Then I
reconfigured.
As before, when I do not specify modprobe.blacklist=radeon, the
display gets stuck with
[ 8.679377] fb0: switching to radeondrmfb from EFI VGA
Before, I could add modprobe.blacklist=radeon to boot to a console.
Now I add modprobe.blacklist=radeon and get
[ 9.507629] fb0: switching to amdgpudrmfb from EFI VGA
It seems like now it is still broken just with amdgpu instead.
