It doesn't. Your BIOS most likely decides to disable the automatic
handling in the Embedded Controller if the OS currently running wants to
use ACPI. It most likely also provides a vendor specific control via the
ACPI EC API, but no support for that is present in DragonFly. The joys
of ACPI. It might also be a slightly different initialisation, but that
is very hard to tell in an abstract mail like this.
