dpkg --get-selections only knows which packages are installed, but not
which versions of them. This is no problem if you have only woody packages
installed. However, if you use apt pining to mix woody and sarge, this
won't work. My suggestion is to create a tarball of your whole system
and extract it on your new one (boot it from a KNOPPIX CD). If this isn't
possible, you can take the output from apt-show-versions and write a perl
script to restore everything.
