The reasoning for hiding Hibernate includes:
1. It doesn't work well for many users on many machines.
2. It's very slow.
3. It's not as useful because users can just suspend.
4. The difference between hibernate and suspend is confusing.
5. There is a lot of work involved with verifying that Hibernates works
and fixing bugs to ensure that it works. This work is not always
completed, and the work that does get done can be channeled to other
useful areas. (In other words, fewer bugs through fewer features to
support).
However, Hibernate works well for some users, so this will be a painful
regression[1].
On some machines hibernate works better than suspend.
Hibernate allows removing power, good for moving a desktop, or swapping
batteries on a laptop.
shutting down is not a good substitute for hibernate, as your state is lost.
2.6.37 got a patch to make hibernation use LZO compression, which should speed
it up a bit
