I know this is old, but this could be useful to others who may be wondering.

You could widgetize your theme: http://codex.wordpress.org/Widgetizing_Themes

Or you could put something like this in your theme:

<?php
	$EmailSubscriptionWidget_options = array(
		'title' => 'Subscribe to my posts',
		'success_msg'=>'Thank you for subscribing',
		'fail_msg' => 'Some unexpected error occurred',
		'submit_button'=>'Subscribe',
		);
	the_widget('EmailSubscriptionWidget', $EmailSubscriptionWidget_options);
	?>

And that is how post necromancy is done!

In case it is of any worth to anyone I edited ianhirschfeld’s code (above) to work with a permlink structure of /%year%/%category%/%post_name%/%post_id%/ :

function remove_page_from_query_string($query_string)
{
	if ($query_string['name'] == 'page' && isset($query_string['year'])) {
		$post_year = $query_string['year'];
		$page_index = $query_string['p'];
		$page_num = $query_string['p'];
		$cat_name = $query_string['category_name'];
		list($delim, $page_index) = split('/', $query_string['page']);
		$query_string = array();
		$query_string['year'] = $post_year;
		$query_string['category_name'] = $cat_name;
		$query_string['paged'] = $page_num;
	}
	return $query_string;
}

add_filter('request', 'remove_page_from_query_string');

Obviously this is nothing that ianhirschfeld’s example didn’t cover, but something for comparison for PHP-unfamiliar users out there.
