Magento - Collection Filter by Array Keep Order

Is it possible to filter a Magento collection using an array of id's BUT have the collection results ordered by the order of the id's passed to the filter.

For example:

$collection = Mage::getModel('catalog/product')
                  ->getCollection()
                  ->addAttributeToFilter('entity_id', array(
                       'in' => array(1, 3, 2),
                   ));

I would like the collection to have products in order, 1,3,2 so as when looping through the collection they come out in that specific order?

The only alternative i currently have is to manually create an array of products:

$productIds = array(1,3,2);
$collection = array();

foreach($productIds as $productId) {
    $collection[] = Mage::getModel('catalog/product')->load($productId);
}

This obviously works but seems like an ugly way to do this.

is there a way to do this purely via magento collections?
