Using snapshot repositories and "apt-get install packagename=version" sounds like a*great* strategy to implement a quick-and-dirty rollback function for apt-get. Do you think it would suffice to analyze history.log and run "apt-get install" with - "package-" for all packages installed by the last update and - add "package=version" for all updated and removed packages? The snapshot it would use is the one of the previous upgrade.
"apt-get install package=version" should remove any packages that conflict with the installation, so you should not have to manually remove anything. The only other thing I did after the downgrade was to "apt-mark hold" the packages affected by the transition that I did not want to remove; this is my preferred tactic for surviving transitions.
