Actually, it already works, so your problem is something different. Set mail_debug=yes and it'll log the reason why hiberation couldn't be done.

I've heard that some clients issue STATUS commands periodically and that causes them not to be hibernated. This is something that probably needs to be implemented by imap-hibernate at some point.
