CheckRDF was announced on Freshmeat yesterday:

CheckRDF is a tool, consisting of a shell script and a Haskell program, for downloading RDF site summaries and showing news in a text file and in an HTML file. It is highly configurable.

It can show new items via tail on the console, or in HTML. It appears to poll all the news sources at a defined interval and shows the new items for each feed group together by polling interval. I haven't actually used it, but it looks decent.
