Yahoo Directory has shown no Toolbar PR in the past, and Google has publicly assured that it's there. I feel that the Toolbar doesn't show PR on directory style pages because Google doesn't want directory listings to be bought or sold for that purpose.
In my experience, BOTW listings have helped rankings, if that's what your worry is.
BOTW edits your listings and keeps a well-maintained directory, and also doesn't accept substandard submissions, and those are all important factors to Google with regard to passing PR.
