Deep sleep only matters if the GSM chip is on.

My expertise pretty much ends here :-) However, it might help if you
power down all extra hardware (bt, gsm, gps, wifi) and then run gpio
from
http://svn.openmoko.org/trunk/src/target/gpio/
and post the results. Here's what I get in this state:
lindi at ginger:~$ om power
bt power 0
gsm power 0
gps power 0
gps keep-on-in-suspend 1
wifi power 0
lindi at ginger:~$ sudo bin/gpio

By looking at
https://svn.openmoko.org/trunk/doc/hardware/GTA02v4/gpio.txt you can
see where each GPIO pin is connected to in the schematics
http://people.gta01.hmw-consulting.de/people/joerg/schematics/GTA02/Schematics_Freerunner-GTA02_A5-A7cumulative_public_RC0.pdf
Does your GPIO output differ from mine?
