--- Comment #4 from Robert Crowston <crowston@protonmail.com> ---
I was able to apply your patch and compile it. Windows boots, and non-GPU
passthrough works correctly. However, the GPU only runs for a few seconds
showing the Windows logo before the screen goes blank. Device manager (via
Remote Desktop) shows "device cannot start".

I'll keep experimenting.
