annotations only in 1.1 ?

I want find all instances of model KeyWord, where ManyToMany field
categories is empty. I think in versieon 1.1 is the appropriate code
like this:

... KeyWord.objects.annotate(cnt = Count(categories)).filter(cnt =
0) ...

What is the similar code in old version 1.0 for resolve the same
result. Should I use extra() method and go to the table level
(SELECT ...) ?
