Need help with vBulletin external.php integration

[Eunos]

I've been using the external feed with type Javascript for years to embed a feed onto the front page of my site. However, things have recently changed. For security, Apache is set to include the following header:
Header set X-Content-Type-Options nosniff

This works fine for Safari and Firefox, but Google Chrome now enforces strict mime types. In Chrome, it throws the following error:
Refused to execute script from 'http://forum.miata.net/vb/external.php?type=js&forumids=82' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

What other options do I have to get the feed to work in Chrome? I know I can set the feed to XML or RSS, but I don't know how to implement it in Javascript.

Here's my current code:

<script type="text/javascript" src="http://forum.miata.net/vb/external.php?type=js&forumids=82"></script> 
<script language="" type="text/javascript"> 
<!-- for (i = 0; i < 8; i++) 
  { 
  document.writeln("<p>"+threads[i].threaddate+": <b>"+threads[i].title+"</b><br>
  <a href=\"http://forum.miata.net/vb/showthread.php?threadid="+threads[i].threadid+"\">Read more...</a></p>"); 
  }
 //--> </script>

Here's a test page: http://www.miata.net/test.html

The test page works with Safari and Firefox,but not with Chrome.
Any suggestions on how to get a feed to work with Chrome?

I found a temporary workaround, which is to put a <filesMatch> directive in Apache so the nosniff header doesn't get sent for external.php. Maybe this is fine as a permanent workaround, but I'd still be interested in knowing if there's a cleaner way.
