OK Im concluding that all video ipods should be able to be updated to run the same spec files as the current 5.5G ipod.
And I looked into the bitrate thing a bit more and I dont think there's anything wrong with your bitrate. The slightly larger bitrate being stated is because that includes the audio, this is totally normal. When I export your video from quicktime but select 'pass-though', it tells me the bitrate for the video is 678kbps, which is lower than the max ipod 768kbps spec for that sort of file. So just to re-iterate, the stated 768kbps ipod bitrate limit for 320x240 baseline h264, is just for the video part, doesnt include audio, so its normal that your video & audio combined can exceed that bitrate.
