Since the docs point to it, but it isn't in the release, maybe the patch could live in http://www.apache.org/dist/httpd/patches/apply_to_2.0.43/ or here http://www.apache.org/dist/httpd/contrib/patches/2.0/.
I have made the patch available here: ftp://ftp.rexursive.com/pub/apache/mod_logio-2.0.43.patch.gz Bojan
