Anyway, if you have the skills you can always modify phpBB to also insert the title of a thread in the url. Appearantly AdSense uses the url to find matching keywords, expecially when no relative ads are available.
Just do a test, go to a page with shows irrelevant ads, say
http://www.example.com/viewtopic.php?t=123
change the url in
http://www.example.com/viewtopic.php?t=123&title=somewidget
chances are that it's now showing ads regarding somewidget.
Of course, you will need to alter the code for that

That happened to me also when I first put up any forum. My AdSense is stable now, but that used to happen when I first put AS on the forums, any of my forums. None of my forums get the generic PHP and Web Hosting ads anymore.
So it might be you need to sit tight for a couple weeks or so until Google figures out what your site is about.
In the meantime while you're waiting you may want to check out PHPbb Hacks for stuff to optimize your forum for the search engines so that you can rank better, receive more unique visitors, and more clicks. It's very simple to do.
