How do you update the status of Facebook subpages?

Facebook status updates occur at the user profile level regardless of what page you're on.  You're able to update a status from the news feed page, the personal profile page, etc...but if you update the status in one place or another, it does the same thing.

Using the API to update a status updates it for a user's profile across the board.  Or am I misunderstanding your question?

You can create business pages and link them to your personal account, see http://www.facebook.com/pages/create.php

How do you use the graph protocol to update the status of the business page, NOT the main personal page?

One more link if you've not seen it.  This article: http://getsatisfaction.com/pingfm/topics/posting_updates_to_facebook_fan_pages_api_supports_it

...suggests you can use the code below.  This was published some time ago, but I believe the feed_publishTemplatizedAction function still works.

$facebook->api_client->feed_publishTemplatizedAction($feed_title_template, $feed_title_data, $feed_body_template, "", $page_id, $feed_image, $feed_image_link);
