I'm just asking because I wrote ACPI support for Dragonfly in estd and I
'm the current maintainer of estd.
If there is a technical reason to have a proprietary implementation I'm 
all for it, but the whole power management stuff is quite fragmented alr
eady with lots of
different implementations that do the same thing slightly different.
