Is that prefetch in terms of a perfomance thing–if so maybe a cache type plugin might help.
And then do what with the page?
You can use get_pages or query_posts to get a specific page. You can wrap the code in the is_home() Conditional Tag.
But here’s an example to get a page…
<?php
$args=array(
'p' => 42,
'post_type' => 'page',
'post_status' => 'publish',
'posts_per_page' => 1,
'caller_get_posts'=> 1
);
$my_query = null;
$my_query = new WP_Query($args);
//$my_query will hold that page
wp_reset_query(); // Restore global post data stomped by the_post().
?>
