actually, no, I just verified this on my ipw2200
"6 (AC) OFF" means "power savings features are disabled"
proof:
# iwpriv eth1 get_power ; iwconfig eth1
eth1 get_power:Power save level: 6 (AC) OFF

notice the wireless device is running and _on_
not sure why you're unable to write to power_level. Can you try using iwpriv to
set the power level and see if that works?
