Собственно, задался этим вопросом. Просто поставить из experimental не получается:
# apt-get install -t experimental docky

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
docky : Depends: libc6 (>= 2.13) but 2.11.2-10 is to be installed or
libc6.1 (>= 2.13) but it is not installable or
libc0.1 (>= 2.13) but it is not installable
Depends: libdbus-glib1.0-cil (>= 0.5) but it is not installable
Depends: libdbus1.0-cil (>= 0.7) but it is not installable
Depends: libglib2.0-0 (>= 2.28.6) but 2.24.2-1 is to be

E: Broken packages

Однако, подолбался, нашел решение проблемы, побеседовал с мейнтейнером docky в debian и оформил на вики - http://wiki.debian.org/DockySqueeze.
«Постю» здесь, ибо:
1. Лор хорошо индексируется;
2. opensource style: может, кому пригодится.
В перспективе это будет deb для squeeze-backports. Ждите-с :)
