I don't have a complete understanding of this. I highly doubt that the
package has been downgraded for etch -- this almost never happens. 

Do you have some examples? One thing I would check is whether
apt-show-versions is lying -- check the version that is installed vs.
the versions that are available. (This should be doable in aptitude, I
think -- if you use the text interface, find the package and select it
then it should show you all the versions of a package that are

Another thing that maybe can affect this is backports. There are also
some bug reports where apt-list-changes seems to get confused, but
they probably don't apply in your case: 


If you are worried about what will happen to your packages, then the
--simulate flag is your friend.
