There are a few threads about supplemental pages in the Google Forum. Some were apparently a glitch and were meant to be fixed. The ones that still remain supplemental are most likely Thin Affiliates or other types of sites with duplicate content. If this applies to your site, don't expect to be unsupplementalled anytime soon, as it is a feature, not a bug.
