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

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:

So enable sshd, get another device ready to ssh into the box, reboot 
with syscons disabled, ssh, play with loading modules :)
