Only common sense. Non-recent machines are barely usable these days. Sure they work well as a firewall or server-in-a-closet, but if you run a desktop or a server that actually does useful work, you're running a relatively recent machine.

If we find that the reset was wired to the launch controller after all, we can back out the change (after we re-evolve technology and Linux; after all we are doomed to keep reinventing it, aren't we?).

Let's see what breaks, if any. I understand the disgust people feel when ACPI is mentioned, but we can't ignore reality.
