Go to the maemo garage site and search for linuxmce and you will find all the various packages. Should be able to just click on the packages and have it install. May need to add a new repository first.
Also, uninstall any old version first.
ps: I am still using OS2006, working quite well - although I am not using it much as I tend to use the keyboard in the lounge and the fiire remote in the back room.
