About 1 years ago, I discussed with my colleague the same function.
Its target wasn't NetBSD but old FreeBSD.

At that time, we thought this functionality should be controllable
with sysctl(8).

kern.shutdown_beep.on		(bool)	beep on shutdown or not
kern.shutdown_beep.duration	(int)	beep time in some unit
kern.shutdown_beep.pitch	(int)	pitch of beep
kern.shutdown_beep.count	(int)	beep number of times

"kern.shutdown_beep.on" might not be needed since it could be
represented with setting "kern.shutdown_beep.count" to 0 or not.
