I am not sure I still have it.  It wasn't finished (thus not 
committed) because it was a lot more complex than I originally 
thought.  We really have to consolidate ACPI state tracking in one 
variable outside of ACPI softc so that it can be atomically tracked 
without complex locking/unlocking layers of various locks, e.g., 
acpi_button from DSDT, fixed buttons from FADT, acpi, giant, etc. :-(
