Wait a second.

The kernel things it knows all power state and what it has to do and
you can't disable this behaviour?

This seeems to be very wrong. That code should be disabled by default.
At least for now, given all the acpi problems. Later we can add a switch
to disable that kernel interface and don't get into any acpi trouble.

I wouldn't trust such a system where the kernel decides to issue a shutdown
because of a wrong event.
