$querystr = "   SELECT $wpdb->posts.* , $wpdb->postmeta.*
                        FROM $wpdb->posts, $wpdb->postmeta
                        WHERE $wpdb->posts.ID = $wpdb->postmeta.post_id 
                        AND $wpdb->postmeta.meta_key = 'Featured_Projects_Page' 
                        AND $wpdb->postmeta.meta_value = 1 
                        AND $wpdb->posts.post_type = 'page'
                        ORDER BY $wpdb->posts.post_date DESC
                     ";
$pageposts = $wpdb->get_results($querystr, OBJECT);

try this, this should work.
