Hi,

there are a lot of different errors in various document regarding acpi
that are wrong.

In 'man acpi' it says that 'hint.acpi.0.disabled' should be placed in
loader.conf.

-------------
LOADER TUNABLES
     Tunables can be set at the loader(8) prompt before booting the kernel
or
     stored in /boot/loader.conf.  Many of these tunables also have a
matching
     sysctl(8) entry for access after boot.
...
     hint.acpi.0.disabled
             Set this to 1 to disable all of ACPI.  If ACPI has been
disabled
             on your system due to a blacklist entry for your BIOS, you
can
             set this to 0 to re-enable ACPI for testing.
...
-------------



In 'man loader' it says:
-------------
     acpi_load
               Unset this to disable automatic loading of the ACPI module.
               See also hint.acpi.0.disabled in device.hints(5).
-------------

In 'man device.hints'
-------------
     The following example disables the ACPI driver:

           hint.acpi.0.disabled="1"
-------------

http://www.freebsd.org/doc/en/articles/laptop/article.html page also
states that it should be in device.hints.


Well, these are the ones I have found. There are a lot of misconfusion in
various forums what to put where and how its done. Maybe its accurate on
both places, but then that should be noted somewhere.
