Yes. In that add_meta_box() takes a screen ID. By default, only certain
screens are supported -- the screens that call do_meta_boxes().

You can then call do_meta_boxes() the way core would, to generate meta
boxes.

Example:

<div class="postbox-container">
<?php
// Parameters: Screen identifier, placement on the screen
(normal/side/column3, etc.), an object that gets passed to the meta box.
do_meta_boxes( $screen->id, 'normal', $post );
?>
</div>

And:

add_meta_box( ... ) where the $page parameter is your $screen->id.
