There's also a decent chance I'm going to be bisecting another amdgpu bug this evening. I am not expecting you or others to do things that I am not willing to do myself.

If amdgpu support is something that is important to IBM, Talos, or other members of OpenPower, then I think reaching out to developers and offering free ppc64le hardware or VM access for kernel development and testing would be an excellent start. Providing automated ppc64le build and boot testing for the amd-staging-drm-next tree would be great as well.

There has been such idea within the OpenPOWER Foundation some time ago,
to have a lab where (primarily) HW vendors would have access and could
test their HW and drivers on a number of different platforms. I suppose
we should revive this idea.
