As of today, all DreamHost customers can enable Passenger (mod_rails) for Ruby on Rails applications.
Briefly, all you do is enable the Ruby on Rails Passenger (mod_rails) option for any existing or new web domain in the DreamHost web control panel. When you then point that domain’s web directory to the public directory of an existing Ruby on Rails application it will work automatically. For more detailed information, check out our Passenger wiki page. You may also want to read additional details in the DreamHost blog post.
