Abr: Nashville:

How was the intonation when you first got the guitar ? Gibson usually ships with 10s, maybe give that a shot. If you still have problems it could be the nut. Good luck.

Have you tried 1-800-4-Gibson ? They have to know something, I hope.

Maybe you can contact this guy, he was selling one on eBay : http://cgi.ebay.com/2005-Gibson-Les-Paul-Supreme-90th-Anniversary-Gold-MINT_W0QQitemZ350021796095QQihZ022QQcategoryZ47072QQcmdZViewItem
