I can sync them with Banshee but in Rhythmbox (Am starting again to use it since it will be the default in 12.04) I can see that Rhythmbox can detect the ipod and see the songs but when I try to drag one to the ipod how can I tell it to sync it so I can remove the iPod and listen to it.

If you are using iOS 5.x, the library that Rhythmbox (and others) use to do this does not yet support the newer database version. If your iOS device has recently been updated, then you simply need to wait for libimobiledevice to be updated (watch the website under Music/Video Synchronization Status for updates).
[edit: 3/11/13 e.m.fields - It seems that the libimobiledevices is supporting up to iOS 6.12 as of this release. ]
