I'm not sure amdgpu works for older cards currently. (Works great for RX 
480!)

You might want to try radeonkms instead.

And if you're using EFI boot with either amdgpu or radeonkms, you need 
to set |hw.syscons.disable=1 in the bootloader because of this:

Which means you won't see anything on the console until the driver is 
loaded.
So enable sshd, get another device ready to ssh into the box, reboot 
with syscons disabled, ssh, play with loading modules :)
