how to enable comment for feed items

[gambit_1607]

in my admin i'm at feed item content type and i've set the comment settings to read/write, but when i load a specific feed item on my page such as mydomain.com/node/137941 there is no comments. i did some research and i came across some code that u can use to manually add in the comment form and comments to the page using the $node variable and the code looks like this

in my template filei i would put...

function phptemplate_preprocess_page(&$vars) {
  $vars['comments'] = $vars['comment_form'] = '';
  if (module_exists('comment') && isset($vars['node'])) {
    $vars['comments'] = comment_render($vars['node']);
    $vars['comment_form'] = drupal_get_form('comment_form', array('nid' => $vars['node']->nid));
  }
}

function phptemplate_preprocess_node(&$vars) {
  $vars['node']->comment = 0;
}

and in my page-node.tpl.php file i would put...

<?php print comment_render($node, $node->cid);?>

i tried this code and it doesn't work. i checked individual feed items from admin under content and they all have comment settings set to disabled. even if i click read/write for comment and save it and come back it's still set to disabled. i think this setting has to be selected to read/write to even use the code above otherwise comment parameters are not passed in the $node variable to bring out the comment form and comments. anyone has any ideas on how i can make the comments appear on my page?
