As of http://core.trac.wordpress.org/changeset/12923, post_type is a 
public query_var by default, though it filters to only allow registered 
post_types that are publicly queryable.  I'm not positive, but I'm 
pretty sure that register_post_type only sets up a rewrite rule for 
/%post_type%/%post_name%/ and doesn't set one up that would allow an 
archive listing of the post_type.  So you would need to set this up 
yourself.
