Sheppy, not sure this has to do with your case, but

I have a whole subdirectory with a greyed out toolbar pagerank - for months.
(whereas I am in top area for the specific Google/DMOZ category list in rankings)

In my case it has to do with the fact that I use a "ç" in the url.
(Google has problems with showing toolbar Pagerank for certain foreign characters)

Check if any pages of your site are in DMOZ/ODP and show a Pagerank there.
