lost S3 shutdown function on debian 8oct2014 image?

dear List,
i’ve changed from debian 7.4 (23apr2014) to bone-debian-7.6-console-armhf-2014-10-08-2gb.img and now i have problems turning off the bbb (rev. A5C). with the previous system i could either press the S3 button or ground pin P9_9 to make the system shut down. but now these two do nothing and i need to ssh in and issue a sudo halt command.
any ideas? do i need to install something? i noted that the 8oct image is minimal and ‘Console’, while the older 23apr image came with a lot of things preinstalled.
