Found a temporary solution.

In this file: /includes/modules/pages/product_reviews/header_php.php
I made the following change:

Find line #43-44 and replace with the following.
Code:
//    $products_name = $review->fields['products_name'] . '<br /><span class="smallText">[' . $review->fields['products_model'] . ']</span>';
//  } else {
Basically I am commenting out the code that Zen Lightbox is mangling which makes the odd/malformed HTML go away. I'm sure the same solution will fix the issue with the Colorbox beta so I'm gonna post this there too..

These were the only files I could related to reviews which has code similar to the code that is getting mangled by the lightbox (specifically the reference to the model number). The write reviews page is probably fine since the I do not see the problem manifest itself there, but you never know.. Dunno if this helps narrow things down, but hoping it helps point things in the right direction..
