That is quite interesting as one of the reasons for Ogg not to be supported in small consumer devices like those mentioned was that traditionally it was a lot harder to do on smaller devices due to the lack of a dedicated chipset, and doing it in software required a reasonable amount of processing power.
Good news if you want to rip your own music to a portable player, but I wonder how relevant ogg-vorbis will be long term with everyone trying to shove us on to DRM formats :-(
