You mean  wmiconfig -i eth0 --wlan disable  ?

This does indeed make a small difference. Some measurements (as
usual, battery current with a battery voltage of 4.0V):

Just booted, sitting idle:		160mA
Associated to AP:			163mA
wmiconfig -i eth0 --wlan disable	160mA
echo 0 >/sys/bus/platform/drivers/gta02-pm-wlan/gta02-pm-wlan.0/power_on
					159mA

The last one is within measurement error from 160mA.
