I haven't checked the spec, but I find it hard to believe. What could possibly be wrong with using S5? It works just fine for normal poweroff, with no wakeup devices enabled. Provided you don't enable the wakeup devices during hibernation, why not use S5? > Unfortunately if we do normal powerdown, we'll confuse ACPI BIOS. We do normal powerdown whenever someone shuts off his computer without hibernating. I haven't noticed any ACPI BIOS confusion from that...
