The iFeedpod freeware app allows you to download your favourite RSS and Atom feeds onto your ipod. I saw this item featured on Wired, so gave it a try -- and it works well. You can choose to have one note per story, or you can group stories from one feed into a single note.
There seems to be a limit on the maximum size of a note, but I think this is an ipod constraint, not a fault of the application. All my favourite feeds worked, except for Gmail. It would be great if there was a way to trigger the app to sync whenever you perform an iTunes update to your pod....
