i'm using knoppix 3.3 too, but with kernel 2.6
battery status and shutdown is running correctly, but i can't switch my
lcd /on/off and i can't change the brightness and volume.
is something wrong in my kernel config?:
ACPI Support = y
	sleep states = y
	ac adappter = y
	battery = y :)
	fan = y
	processor = n
	asus = n
	toshiba = n
	debug statements = n
	relaxed aml = n
