Interesting. I have not seen a swap partition on a Kindle PW4 so must have been introduced in a later generation. The only message I've seen on screen after pressing the power button up is Waking up. If nothing else, hibernate would require writing everything to a file before powering down the system and that would require logic to differentiate between a power on loading everything from disk and a resume from hibernate restoring RAM and registers from the disk file. In that case, a hibernate would need to read the memory size plus additional status information so ~512MB which would be on the slow side. There is an memory swap but that is not going to be useful for hibernation since, logically enough, it's in memory which will be lost when memory is powered off.
fdisk -l for the disk partitions
grep "VmSwap:" /proc/*/status | awk '{swapped+=$2} END {print
swapped/1024" MB"}' for any swap memory usage
