Firmware used to mean "let the bios do the whole > suspend", platform means "linux does the suspend, but we tell bios we > are doing it", shutdown means "linux does the suspend, does not tell > anyone". Well, actually, "let the bios do the whole suspend" should be implemented by a new PM_SUSPEND_FIRMWAREDISK mode that can be used instead of "disk" and is invoked through pm_ops directly w/o hitting the disk.c code. That would be the right way to invoke such a mode, however, currently, no platforms even have such a mode as far as I can tell. johannes
