Unfortunately, I can't create temporary pages as 2by4 has suggested because the ones with some uppercase letters are really the exact same pages as the ones that are correct with all lowercase letters.

Windows servers allow you to call a page with uppercase letters and it will return results for those pages, but it does not allow you to have actual unique pages with and without upper case letters. So when you call a page with uppercase letters and call a page with lowercase letters, although the urls will be different and in Googles eye unique, the page is really the exact same page on the server. So you can't do a 301 meta redirect because you will be also redirecting the ones with all lowercase as well (albeit you'll be redirect those to themselves). I think that will cause even more problems.

Additionally, if you 301 them, it will just move them to the supplemental index and IMO that will not fix the problem because Google it appears still levies the duplicate content penalty even if one of the duplicates is in the supplemental index. Therefore you can only get the duplicate content penalty to go away if one of the duplicates is removed completely from Google's indexes (the main index and/or supplemental index, but preferably the one in the supplemental index)
