I updated the bug item earlier today, kstat reports the following:

# kstat -m battery
module: battery				instance: 0
name:	battery warning			class:	misc
	crtime				42.683940508
	enabled				0
	low capacity threshold		0
	snaptime			7215.276906032
	warn capacity threshold		0

module:	battery				instance: 0
name:	power				class:	misc
	crtime				42.683940508
	snaptime			7215.279837494
	supported_battery_count		0
	system power			AC
