How exactly can you see it? :)

If you can see actual text on the screen after the loader and before 
the driver is loaded, you haven't actually turned the efi framebuffer 
off.

Make sure you're actually booting with hw.syscons.disable=1 (garbage 
should be on screen after the bootloader starts the kernel), disable 
the amdgpu auto loading and try loading it manually over SSH.

raven is raven, there's no 'vega8' firmware AFAIK.
