The packaging is done, you can find my results using deb http://mentors.debian.net/debian unstable main contrib non-free deb-src http://mentors.debian.net/debian unstable main contrib non-free (after Packages.gz is updated by the site)
or have a look at http://mentors.debian.net/debian/dists/unstable/main/binary-i386/avrdude/ I'm still looking for a sponsor to do the review and 'real' upload. Please contact me, if you are interested! (Or if you have a suggestion who to ask for it ;-)
