[Gta04-owner] Modem off

Hi,
i wonder if modem powering off works as it should. Attached is charging graph 
taken from my GTA04.

You can see power consumption for:

1/ normal suspend 13:09 to 14:26, discharging current is 24mA

2/ suspend when modem was turned off as documented here [1] from 14:32 to 
16:11, discharging current is 37mA

3/ device turned off with modem turned off from 16:11 to 16:59, discharging 
current is 14mA

What is strange - i'd expect current at 2/ to be under 24mA and it should tell 
us how much modem eats.

The case 3 might not be very accurate, because in those 14mA is accounted 
power used for device booting. I'll retry it using longer time period.

Btw new QtMoko with this charging graph feature is now building.

Regards

Radek
