Why can’t you just add the blog as an RSS feed to the facebook fan page? You can do this for a fan page, just as you can for your personal page, though it can be a bit of a pain to find the option.
Once you have added your blog, facebook will automatically add all your blog posts to the fan pages as notes.
I’ve written instructions on how to add this here.
[edit]Sorry…. Just realised this is a very old thread…..
