Low Power / Hibernate in Gadgeteer

Figure its time to up my prototypes to the next level and start adding hibernation etc for power conservation, so with some of the gas sensors that I picked up, I’d like to collect a reading every x minutes and kick the Cerberus into hibernate and or low power mode between readings. I looked at http://wiki.tinyclr.com/index.php?title=Low_Power but couldn’t find any of that stuff for the Cerberus running the latest 4.2 firmware etc. Any suggestions as to where to look next?

The gas sensors are nice as you can turn the heaters on/off which is nice for reducing power usage, but I want to take that next step.

GHI premium libs include power and watchdog. In the open source offers it is left to user to implement.
