Paginer un find first suivi d'un contain ?

Salutations,

Je bloque un peu sur un petit truc, et je cherche à paginer les articles qui appartiennent à telle ou telle catégorie, mais je ne sais pas trop comment faire :/

Mon controller :

function show_category($category){
$this->loadModel('Category');
$d'category'] = $this->Category->find('first', array(
    'conditions' => array('slug' => $category),
    'contain' => array('Post' => array('Media', 'order' => 'Post.created ASC', 'conditions' => array('Post.online = 1', 'Post.created <= NOW()')))
));
$this->set($d);
}

En gros comment paginer ce find first (qui contient d'autres array !) ou paginer l'array en lui même :S

Je vous donne le debug de $d'category'] :

array(
    'Category' => array(
        'id' => '1',
        'name' => 'audio',
        'slug' => 'audio',
        'count' => '2',
        'link' => array(
            'controller' => 'posts',
            'action' => 'show_category',
            'slug' => 'audio'
        )
    ),
    'Post' => array(
        (int) 0 => array(
            'id' => '1',
            'name' => 'Mon premier article',
            'slug' => 'mon-premier-article',
            'description' => '<p>Ma description.</p>',
            'media_id' => '394',
            'created' => '1995-11-11 16:35:00',

            'CategoriesPost' => array(

                'category_id' => '1'
            ),
            'Media' => array(

                (int) 2 => array(

                    'filef' => 'Uploads/Posts/2012/Nov/1/atika_atikawa_%dx%d.jpg'
                )
            )
        ),
        (int) 1 => array(
            'id' => '2',
            'name' => 'Mon second article',
            'slug' => 'mon-second-article',
            'description' => '<p>Ma desc...</p>',

            'Media' => array(
                (int) 0 => array(

                    'ref' => 'Post',
                    'ref_id' => '2',
                    'file' => 'Uploads/Posts/2012/Nov/2/co.jpg',
                    'position' => '0',
                    'show' => '0',

                    'show' => '0',
                    'filef' => 'Uploads/Posts/2012/Nov/2/ET_%dx%d.jpg'
                )
            )
        )
    )
)

Il serait préférable de ne pas perdre l'index Media en faisant la pagination, car je l'utilise pour mon image de page à la une :S

Merci d'avance :)
