If this is actually hibernation, it *is* powering off, just with an unusual poweron process (restoring the RAM image from nonvolatile storage, i.e. flash). (The other common approach is commonly called "suspending": powering off the CPU, but leaving the RAM powered. Are you sure this isn't what the Oasis etc are doing? it's much faster to restore from, still saves a lot of power, and doesn't burn through flash lifetime the way writing most of the RAM contents to it on every sleep would.)
