This is a little smarter. No define yet as first need to find out if Google provides an image to indicate when an item s not available through Google Checkout.

Code:
<!-- bof Google Checkout -->
<?php
  if ($products_virtual = 1) {
     if(MODULE_PAYMENT_GOOGLECHECKOUT_VIRTUAL_GOODS == 'True') {
	echo '<div class="warning">This download product is available through regular checkout. However it currently is not available via Google Checkout.<br /><br /></div>';
	}
  }	
?>
<!-- eof Google Checkout -->
