Doug, please delete unneeded context from mails, paging through screen
after screen of irrelevant text on the off chance of finding content
gets old fast so it's likely that some or all what you're saying will be
missed either through boredone or error.

No, this is not the case.  The suspend mode settings are a completely
different set of settings activated when the system goes into suspend
with explicit hardware support.  If no configuration for this mode is
provided then

As ever the hardware configuration won't be touched by the kernel unless
it's explicitly told to do something.
