Interesting. Are you 100% sure you're booting with UEFI, not CSM/legacy?

Maybe radeonkms doesn't conflict anymore. Maybe this depends on the GPU 
model or something?

For amdgpu (RX 480), it's not an error about disabling acceleration, 
the amdgpu driver *completely* fails to load when EFI framebuffer is 
active. And I retested a few weeks ago. No one fixed this specifically 
yet, so I'm not expecting it to magically stop conflicting…
