Facebook has updated their Groups allowing this feature. This does not work for old groups though only newly created groups.
The settings for new groups can be seen in the upper right of that group page.
Facebook doesn't offer an RSS feed but you may use a service like NutshellMail to get all the Facebook updates in an email newsletter. Pass this newsletter to FeedMyInbox.com and there you have an RSS feed of all your updates.
Best Answer
You can get the rss feed of a page from http://www.facebook.com/feeds/page.php?format=atom10&id=xxxxx . It includes any post to your page but sadly not the comments.
