So now it reached to my tree, and noticed this "default ACPI".

After reading the patch description, I understand the reason behind
it, but still I'd say this would confuse users.  For example, I was
quite surprised and almost proceeded to build this unnecessary just
because of the expectation to be default "N" in a standard config.

The distros would enable in anyway, so you don't have to care much.
The question is which target should we satisfy more: users who don't
need to turn this on, or users who need this.  In probability, I'd bet
the former :)
