You'd normally need this enabled to get a fb display on the console, but I 
don't know if this would be provided by proprietary drivers instead for your 
card - see below.

It could be both.  I don't think there's any Linux firmware released yet for 
this card - but I don't follow the latest & greatest so I could be wrong.  
You'd need the AMD amdgpu-pro on top of the amdgpu driver, to bring in the 
proprietary OpenGL, OpenCL, Vulkan and AMF components:
