so i have flashed
uImage-moredrivers-GTA02_andy-tracking_c08a4eb0f4266a72.bin and used
this Qi qi-s3c2442-andy_7cc3d38184ae30bd.udfu which surprisingly loaded
the kernel from NAND??? (flash card outside on the table:
root at om-gta02:~# uname -a
Linux om-gta02 2.6.28-GTA02_andy-tracking_c08a4eb0f4266a72-mokodev #168
PREEMPT Mon Nov 17 17:04:29 GMT 2008 armv4tl unknown

wsod again, i tried echo mem > /sys/power/state and then did suspend by
the button... i think... :) 

but this kernel doesn't have
/sys/class/i2c-adapter/i2c-0/0-0073/glamo3362.0/regs to send any
status...
