Yes, it's strange. I think the key is wlan power management. Did you set 
it to "on"?

    iwconfig wlan0 power on

With this setting and a running wlan I get lower power consumption than 
with a powered down wlan. Without power management, consumption is 1 W 
higher, and doesn't appear to depend much on the rfkill state.

Greetings,
Bernd
