Take a look at Synaptic Menu you can select a package and then go to
Package > Force Version, you can only force one package at a time
but, yes you can downgrade. I can down grade a couple hundred
packages without much problem, depends on the user.

Oh, that's heartening! Does Synaptic use a different method
from dpkg? The man page for the latter says (and the warnings
look very pretty in red):

 --force-things, --no-force-things, --refuse-things


  Warning: These options are mostly intended to be used by experts
  only. Using them without fully understanding their effects  may
  break your whole system.


  downgrade(*):  Install a package, even if newer version of it is
  already installed.

  Warning: At present dpkg does not do any dependency checking  on
  downgrades  and  therefore  will  not  warn you if the downgrade
  breaks the dependency of some other package. This can have seri‐
  ous  side  effects,  downgrading essential system components can
  even make your whole system unusable. Use with care.


Hi David, Synaptic will not let you install a broken package. If you are running sid/testing sometimes a package version will become obsolete and need a change or a video driver version is not working and needs a change, etc. If you're running in a GUI Synaptic is handy to have installed. And yes, it's using "dpkg".
