What you're experiencing sounds suspiciously like what happened to me
when I nuked by C library...
Fortunately, if you have the deb of libc6 around (on your install CD),
you may be able to recover.

Do this...

I suspect it will be.
Then: reinstall libc6... which you will probably have to do by hand as
I'm guessing that dpkg won't be working. Assuming that what is
normally your root filesystem is mounted on /mnt, and has a usable and
empty tmp in it, copy the libc6 deb from your install CD into /mnt/tmp
and then
cd /mnt/tmp
ar -x libc6_*.deb
tar xzf data.tar.gz
ls -l (so you can see what's just happened...)
cp -a lib/* /mnt/lib
cp -a sbin/* /mnt/sbin
(and so on for other relevant directories)
cd /
chroot /mnt /sbin/ldconfig
Then try the reboot... with a bit of luck (and if my diagnosis is
correct) you'll be up again.
