Certo che si può fare, io lo faccio abitualmente per openoffice ecc.
In realtà quello che sto per andare a descrivere è il modo più complicato (all'inizio) ma poi te ne puoi dimenticare; esiste un modo più facile: dai apt-get -t sid install nome_pacchetto e d'ora in poi invece di apt-get upgrade dai apt-get dist-upgrade.
Il metodo difficile:
al solito devi creare il file /etc/apt/preferences, mettere i repository che ti interessano in /etc/apt/sources.list.
Personalmente non metto alcuna default release in /etc/apt/apt.conf (a patto però che metti tutti i repository nel preferences).

Questo che do è il mio preferences: c'è un sacco di roba ma funziona. (da prendere come esempio, con molta cautela.)
