I've had to run the atom feed through FeedBurner first - and then that feed through FeedWordPress.
I've also noticed that I seem to get some sort of error from feedburner when clicking on certain linnks in the feed.
To avoid this, I've configured the permalinks on FWP to point to the copy on the WP server rather than the original one at Facebook.
I've still plenty more playing around to do - but in essence, it's working :)
