I'd like to land this patch, I realise people have NAKed it but for
consistency across drivers I'm going to ask we land it or something
like it.

The main use case for this is actually where you have amdgpu crashes
on load, and you want to debug them, people boot with nomodeset and
then modprobe amdgpu modeset=1 to get the crash in a running system.
This works for numerous other drivers, I'm not sure why amdgpu needs
to be the odd one out.
