Does FBSD support 'software suspend' ?

Thanks for the info.

So, what i surmise is that : the 'suspend to disk' feature in BSD is
currently  h/w dependent i.e  BSD does not have a 'software suspend'
feature like in linux provided by suspend2 (http://www.suspend2.net).

How useful is this feature(s/w suspend) , if implemented ? I am planning to
take up its development as my final year project.I have not decided for
final to take it up;any suggestions/remarks regarding its use and feasiblity
would be very very valuable in helping me to take the right decision.

TIA.
