With some of the moving around of code in Rails 3 Authlogic is broken. This is a quick fix, and not the solution. Add the following to your Session class:

class UserSession < Authlogic::Session::Base
  def self.model_name
    ActiveModel::Name.new(self.to_s)
  end
end

You should be good to go. I have to read up on the process for patching authlogic. Right now it is late and I am sick. I hope this quick fix gets someone going.
