Comment 2 for bug 109915

I'm afraid this is not possible, at least not for the Free Software repos.
uade contains lots of Amiga code which isn't under Open Source license and it could only be hosted in the non-free Debian repo or in Medibuntu.
There is already a package for Jaunty 32bit here: http://morgoth.free.fr/ubports/ but no 64bit yet.
