Make the "about" page default home page on all new blogs

I need to find out how to set the default home page to a specific page on all new blogs. Since the "About" page is written by wpmu-functions.php when each new blog is created, I can hard code the content into this file, and the page content will be created when each new site is set up. What I am struggling to do, however, is set that page as the default home page.

Basically, I need to add a few lines to to the wpmu-functions.php file to set the option 'show_on_front' to page and 'page_on_front' to 2.

Ideas anyone?
