I just stabled it on amd64. No bugs ever ;-) To test, just emerge and run $ rsstail -u http://planet.gentoo.org/rss20.xml -l -p @net-news: I hope you don't mind me bumping it and requesting stable. If that's a problem for you, I can add myself to metadata (if you like).
Works just fine for me on x86.
