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.
