do you know your partitions well? if so, either use a livecd or some
other working linux system (if available)
you need to mount the root partition of the non-working system,
somewhere, i'll assume you're going to mount at on /media
if you have seperate /boot, /usr, /var, /home partitions, mount them
with respect to the mounted root partition. that is, mount /home under
/media/home and so on, if you don't have seperate partitions then ignore
this.
after you're done mounting, open a terminal (konsole), and type

sudo chroot /media /bin/sh

now, you are working inside the mounted system, use dpkg, or the
brilliant idea suggested by sundar in this thread to get the list of
packages.
