I had a go at doing this a while ago but didn't know about bit6 then. I tried updating my patch today but haven't got my Sansa with my to try it out. I've attached it so someone with a Sansa can try it out. Since I haven't actually tested, there could be plenty of bugs floating around. It does at least compile cleanly.
