title: Magento: Get a custom attribute value without loading the entire product
body: <p>At the moment I use this to get a custom attribute value:</p>
  
  <pre><code>$_item = $this-&gt;getProduct()-&gt;getId();
  $_product = $_product = Mage::getModel('catalog/product')-&gt;load($_item);  
  $optionvalue = $_product-&gt;getCustomAttributeValue();
  echo $optionvalue;
  </code></pre>
  
  <p>I wonder is there an easier way to get this custom value without loading the entire product?</p>
