Is this with 1.5.1?  The caching has been changed a bit in 1.5.1.  You
shouldn't see multiple queries, especially not with categories since we
query all categories up front.  You might see multiple queries if your
plugin is pulling in posts that are not part of the main query.  The
plugin can use update_post_caches() or update_post_cache() to avoid
multiple queries.
