Hm, the only difference i could find is that on 2.6.29 the mmc is powered
while on 2.6.34 it is not.

Comment:
I powered my gta02V5 with only usb and added a 0.5 ohm resistor to the usb
Vcc. I then got a friend measure the voltage over that resistor with
picoscope. The following screenshot shows how the phone goes to suspend
and wakes from it (everything is off except the backlight which is at
maximum):

Here are some current measurements done with usb and 0.1 ohm resistor (I
said 0.5 ohm previously but that was false info):
