i cant help very much here since i dont understand the kernel and the HW much 

I would try boot to NAND and then reboot first with the modem powered on and 
then with the modem powered off that makes difference.

The modem can be powered from command line sending 0 or 1 to gpio186 - this is 
described in gta04 manual, something like:

	echo 1 >/sys/devices/virtual/gpio/gpio186/value
	some sleep
	echo 0 >/sys/devices/virtual/gpio/gpio186/value

You can also try calling your number - when the modem is powered on it will 

I'd also try removing battery and booting again.

But i really dont have much clue what next...
