SubjectRe: [Q] How to tell we're using the KMS (during suspend/resume) outside the graphics driver
As far as the ACPI video driver goes, acpi_get_physical_pci_device() 
will give you something to work with. For the console-switching case, I
think the most reasonable plan is probably to add a flag to the console
drivers to indicate whether or not they support reprogramming the
hardware themselves, and then walk all active console drivers. There'd
need to be a way for fb drivers to tell fbcon that they can handle it.
