Yes, post it.

# cat /sys/power/image_size
524288000
# echo disk >/sys/power/state
error
# echo disk >/sys/power/state
error
# echo $((400*1024*1024)) > /sys/power/image_size
# echo disk >/sys/power/state
ok
# dmesg|grep Memory:
Memory: 1027160k/1048256k available (2559k kernel code, 20348k reserved,
1114k data, 188k init)
