> Even this is not that unusual; AFAIK, in recent AMD x86 processors, a separate built-in ARM core takes control on power up,
Good point. I think most modern motherboards (and all server boards) have a "management engine" that prepares the board on power up and even serves some functions during operation. I believe that that's what supports IPMI/iDRAC even when the host is running.
I don't think that changes the situation WRT the variety of H/W for the Pis through their history and even at present.
