Try this in .irbrc:

module IRB
   def IRB.start_session(*args)
     unless $irb
       IRB.setup nil
     end

     workspace = WorkSpace.new(*args)

     if @CONF[:SCRIPT] ## normally, set by parse_opts
       $irb = Irb.new(workspace, @CONF[:SCRIPT])
     else
       $irb = Irb.new(workspace)
     end

     @CONF[:IRB_RC].call($irb.context) if @CONF[:IRB_RC]
     @CONF[:MAIN_CONTEXT] = $irb.context

     trap 'INT' do
       $irb.signal_handle
     end

     custom_configuration if defined?(IRB.custom_configuration)

     catch :IRB_EXIT do
       $irb.eval_input
     end
   end
end

x = Object.new
puts "\nStarted irb shell for x"
IRB.start_session(x)
