Argh. I finally got X configured and running in debian, and now I can't get the card to bind to amdgpu no matter what I do. The normal method--a rescan--results in it going straight back to pci-stub. If I unbind, then rmmod pci-stub, then rescan, it still refuses to bind to amdgpu. I think I'll just have to compile X and amdgpu in Arch after all.
