I don't think the design of linux really affects this very much. The primary issue with hibernation is the interaction with hardware can be quite complex, and the development effort behind linux drivers is generally less than what goes into the drivers on other platforms (and often has less documentation to go on). The core of linux can handle hibernation just fine in my experience, if you're on hardware which linux supports well enough.
