I had similar issues with under Vista generated programs not running
under 2K (unfortunately I have to support it). This behavior came from
the .dll dependency tracking of py2exe, which included a OS .dll into
the dist output.

These are the steps I toke to find the offending .dll
* generated a "flat" directory (the .dll's not packed into
  with options = { [...], 'bundle_files': 3 }
* extracted the not loadable extension from
* examined the dependencies of this module with Microsoft's
  "Dependency Walker" (you can find it somewhere in the MSDN)
* added the superfluous .dll to the
  options = { [...], 'dll_excludes': ['offending.dll'] } parameter
