Repositioning node comments

A strange quirk in Drupal 6 hard-codes comment rendering into the node module. This makes it quite difficult to reposition comments, for instance under a set of tabs in the node template. Attempting this brings you crashing into the most dreaded rampart of Drupal theming; moving something out of it's vertical stack:
comments displayed as tab
comment_render($node) can easily be placed in your node template, but how on earth can the original display be removed? comment_render() is called by node_show(), which contains this nugget:

if (function_exists('comment_render') && $node->comment) {
  $output .= comment_render($node, $cid);

Ouch. (Thankfully, this has been fixed in Drupal 7.)

While it's tempting to fake it with jQuery, or CSS positioning, there is a way to fix this by overriding the page callback for node rendering. Here's a quick module that implements this solution:
