In 1.2 you can use Model::isUnique() method.
var $validate = array(
'username' => array(
'Username must be between 6 and 255 characters long.'
=> array(
'rule' => array('between', 6, 255),
'required' => true,
),
'Name must be unique.' => array(
'rule' => array('isUnique', 'name'),
'on' => 'create'
),
),
'profile' => array(
'Profile must be unique.' => array(
'rule' => array('isUnique', 'profile'),
'on' => 'create'
),
),
);
