DRY-ified (from the comments of that same page):

module ActiveRecord
  class Base  
    def self.to_select(index={}, conditions=nil)
      find(:all, :conditions => conditions).to_select(index)
    end
  end
end

class Array
  def to_select(index)
    self.collect { |x| [x.const_get(index),x.id] }
  end
end
