I found this information on www.mobileread.com from Hadrien-Feedbooks.com Co-Founder.

Feedbooks is providing an easy way for Kindle users to download and read RSS feeds directly on their device:

You can create a file for a single feed: http://www.feedbooks.com/feed
... or you can create a newspaper with multiple feeds: http://www.feedbooks.com/newspaper/create

Generate a Mobipocket/Kindle file and transfer the file to your Kindle through USB or e-mail

Once the file is on your Kindle, you can directly update your feeds inside the file, through the link on the cover or in the main menu of the file
You can also subscribe to these feeds/newspapers from the main website and download those subscriptions from the mobile website: http://feedbooks.mobi

There are some premade newspapers available at http://www.feedbooks.com/news
