Here's something else I'm gonna try

http://www.hotscripts.com/Detailed/74064.html

It says in the documentation of this script that we need "sitemap.xml"....and that freebie site also converts the stuff to sitemap.xml (which you upload and tell google where it is) so I assumed that the sitemap.php you supplied worked in the same manner. That's when I copied the source code of sitemap.php and removed the offending link and saved it as sitemap.xml which google liked...so IDK.
