how to enable accessibility on envrionment based on D-Bus?

Hi, All,
I am working on a system based on D-Bus. And I am trying to use accessibility 
technology in the system.
Do you know some tips that can help me enable accessibility on such system?
------------------  my operations ------------------
1. I have installed necessary packages (including bonobo and pyatspi)
2. root@system1:/# export GTK_MODULES=gail:hail:atk-bridge
3. run the at-spi-registryd:
        root@system1#/usr/lib/at-spi/at-spi-registryd &
        [1] 5375
        root@system1:/# Xlib:  extension "XEVIE" missing on display ":0.0".
4. start the gnome-text-editor and do some test on pyspi:
        root@system1:/# gnome-text-editor &
        root@system1:/# python
        Python 2.5.1 (r251:54863, Oct  5 2007, 13:40:04)
        [GCC 4.2.1 (Ubuntu 4.2.1-5ubuntu4)] on linux2
        Type "help", "copyright", "credits" or "license" for more information.
        >>> import pyatspi
        >>> reg=pyatspi.Registry        
        >>> print reg
        <pyatspi.registry.Registry object at 0x824032c>
        >>> desk=reg.getDesktop(0)
        >> print desk
        [unknown | main]
No application registered in ATSPI.
