Need to enable some plugin options in Paste

Ok, I've tried editing the tinymce_profile_form_build function in tinymce.module. I added the following options. Some work, some don't seem to work. In particular, 'paste_auto_cleanup_on_paste' doesn't seem
to work in IE6 or IE7. (I don't expect it to work in non-IE browsers, based on the TinyMCE documentation.) Any suggestions from someone who has successfully implemented TinyMCE options in the past would be greatly appreciated.
