So far, resume from suspend-to-RAM (ACPI S3) is broken on all of the systems I have tested, so it is probably safe to assume it to be broken everywhere. I'm quite confident that this is not something that went in through the PM tree, because I was running those changes on the systems that turn out to be broken now. It looks like the the ACPI waking vector mechanism stopped working, so I'm suspecting some x86 changes having to do with virtual-to-physical address mapping. I've just started bisection.
