wp_get_archives for a specific category?

I did this in a relatively complicated way using a custom query. I did not know about Smart Archives Reloaded so I wrote code myself. But it works. Replace your category ID for “term_taxonomy.term_id”

<?php
                     global $wpdb, $wp_locale;
                    $query = "select YEAR(post_date) AS `year`, MONTH(post_date) AS `month`, count(ID) as posts from $wpdb->posts,  $wpdb->term_taxonomy, $wpdb->term_relationships 
                        WHERE $wpdb->posts.post_status="publish" 
                        AND $wpdb->posts.post_type="post"
                        AND $wpdb->term_taxonomy.term_id = 11
                        AND $wpdb->posts.ID = $wpdb->term_relationships.object_id
                        AND $wpdb->term_taxonomy.term_taxonomy_id = $wpdb->term_relationships.term_taxonomy_id
                     GROUP BY YEAR(post_date), MONTH(post_date) ORDER BY post_date DESC"; 
                     $arcresults = $wpdb->get_results($query); 
                    foreach ($arcresults as $arcresult): 
                    $text = sprintf(__('%1$s %2$d'), $wp_locale->get_month($arcresult->month), $arcresult->year);?>
                    <li><a href="https://wordpress.stackexchange.com/questions/13968/<?php bloginfo("url') ?>/[your_category_base]/[your_category_name]/date/<?php echo $arcresult->year; ?>/<?php echo str_pad($arcresult->month, 2, '0', STR_PAD_LEFT); ?>"><?php echo $text;  ?> </li>
                      <?php endforeach; ?> 

Writing this I was helped by looking at http://core.trac.wordpress.org/browser/tags/3.2.1/wp-includes/general-template.php where wp_get_archives is defined.

And used the code found here (put in functions.php):

to create permalinks for archives for one category in the form of
http://example.com/category_base/category_name/date/YYYY/MM
