Only the main pages are indexed, with keywords appearing for the 'alt text' and 'page title'. Non of the iframe context has every been indexed. (have done extensive testing)
If you want the iframe's indexed - use a sitemap and link directly into the iframe page - remembering to force the orphan iframe back into it's frameset.
Hope this helps
