Replying only to the last sentence:  Add a DTMLMethod in the root of your Zope
(call it maybe "debug_request"), with the following body:

  <dtml-var standard_html_header>
  <dtml-var REQUEST>
  <dtml-var standard_html_footer>

This works fine on 2.1.4+ -- they only suppress the "direct traversal" of
REQUEST.

Tres.
