I've never downgrade using apt, but with synaptic it's not too hard, 
just go to the menu, package, force version and then to edit, fix 
packages.  The fix package part really only checks to see no package is 
broken, but you must do it or risk losing all your current settings and 
have to start over.

Hope that helps.
