Well, there's this BBC World news widget:

But if you don't like that, you can get any RSS feed to be displayed on your Chumby using this widget:

I have several instances of this widget queued up in my default channel, each displaying a different feed.
There's also a nice RSS reader in the Japanese section that used to work very well (in English) but recently stopped working.

The BBC has tons of RSS feeds available here:

And The Washington Post has quite a few available here:

Hope you find some that you like!
