When your site has pages in our supplemental index, it does *not* indicate that your site has been penalized. In particular, we do not move a site's pages from our main to our supplemental index in response to any violations of our Webmaster Guidelines..... You can expect to see a fresher supplemental index in the coming quarters.

Translation: Supplemental means it goes to a lesser index because it's not valuable enough and thus isn't refreshed as often, i.e., you've been penalized.

Solution: get more links for those pages.

This is nigh to impossible without paying for links as most directories won't let you link to inside pages and Google penalizes sites for buying too many links. If you only have a few pages to buy links for maybe this will work but woe to mega sites needing links.

Last Resort: Buy Adwords.

Of course this is Google's main goal in the first place.

However if you do buy AdWords be prepared to keep it running forever or they will drop your KW rank for all major KW--speaking from experience here.

Which is another Google goal.
