Well, first off, documentation is one thing, actually changing
behavior is something entirely different.

Theory and practice are *not* the same.

The other worry I have is that I'd be happier if it's still visible in
/sys/bus/acpi/ etc. Again, it's one thing to not react to it
programmatically, and another thing entirely to actually hide the
information from the rest of the system.

If I read that patch right, it will be hidden from sysfs too. But
Maybe I'm mistaken.
