All internal pages reduced to PR0 after www 301 redirect.

Home page still PR5

[cleanup]

Well its been a month now since Googles last PR update, during which all my internal pages went to PR0.
They used to be PR5/4 etc.

I think this is because Google STIIIILLLLLL has my pages listed in the index under non-www eight months after I redirected all requests to www via a 301.

So obviously Google does not know about the www pages in spite of the redirect and therefore when someone access a page the get served the www version that has PR of 0 ie unknown to Google.

What can I do to get Google to somehow crawl the damn pages and put them in the index under the correct title of www and hence have PR retruned to them?

Anyone else here seen/solved the problem?
