part of it depends not only registration of the custom display widget, but  
also how your rendering the display, ie. if your using formlib, just using  
a displayformbase should do it, if your using zope.app.form directly  
you'll might also need to specify that you want to specify IDisplayWidget  
as the type when rendering, ie. its hard to say without the other piece of  
this, namely how your rendering the form.
