I installed Ubuntu 12.04 on an Intellibook (Intel® Atom™ N450 processor, Intel® NM10 Express Chipset, Intel® GMA 3150), activated a swap partition and tried pm-hibernate. It seems to work but when I switch back on, the system will boot without restoring the old state.

Is there a way to activate hibernation on Intellibook or is it not working on the given hardware?

If sudo pm-hibernate doesn't completely work (hibernate and resume), hibernation isn't compatible with your current hardware.

You can try the alternative TuxOnIce hibernation method which has somewhat better compatibility, but no guarantees.

Please see section B of this answer for how to try TuxOnIce hibernation.
