As far as I know, AMD does not have any "evil brother" of Intel ME. It only has AMD PSP (Platform Secure Processor) that is built-in to CPU. So, I don't think that cutting a PCH from AMD CPU has any practical value: even if the platform will boot after such a radical change to computer's hardware, you'll lose a lot of essential stuff like USB ports
