However, while Linux successfully starts the secondary cores when
the system first boots, it fails when the system resumes from "S3".
Oh boy...

Turns out the firmware was, in fact, (upon resume) stomping over parts
of the Linux memory image in RAM, triggering all kinds of "interesting"
nasal demons when Linux ran (or, more accurately, limped).
Well... firmware is always fun :-). Good that it got solved...
