Smart Package Manager has the capability to downgrade a package and
it's dependent pacakges. All packages need to be available on enabled
repositories. Install smart-gui from Extras, click on the version that
you want, and smart will figure out the package combination that meets
your selection. Although I haven't tried downgrading with Pirut I
believe it too has that capability.
