   I get these types of questions on the debianhelp.org site all the time.

   Debian wasn't designed to be downgraded in that way, so you're treading
on thin ice.  My advice would be to reinstall.  If you save your config
files and other important stuff and then do a:

dpkg --get-selections > file

   followed by an barebones install and then a

dpkg --set-selections < file
apt-get dselect-upgrade

   and it'll make short work of the reinstall.  (You'll get a few errors
in the above command for testing packages that would not be in the older
release, but it'll work fine.)  But of course reinstalling isn't what you
want to do. :-)

   The other answer is very risky -- don't blame me if your system
breaks.  You could get the woody/testing versions (downgrading all the way
to stable would be even harder and riskier) of all of the various packages
that you have installed, throw them into a subdirectory, and then do a
"dpkg -i *.deb".  You'll have to do repeated "dpkg -i *.deb" commands
along with a few "dpkg --force-remove-essential --purge <packagename>"
commands.

   This is not for the faint of heart and you could easily turn your
system into mush.  Again, the reinstall is probably quicker.
