install the package mkinitrd-tools and modify /etc/mkinitrd/mkinitrd.conf so
$ROOT points to your new root partition (autodetection will fail in chroot).
These steps are only required if you want to use one of the Debian
kernel-images.

apt-get install initrd-tools
============================	check /etc/mkinitrd/mkinitrd.conf   (SCSI)
MODULES=most

DELAY=0
ROOT=/dev/sda1

# This controls the permission of the resulting initrd image.
UMASK=022
# generate the initrd image.

----------------------------	chroot# 
mount /proc /proc -t proc
apt-get install kernel-image-2.4.18-686
apt-get install kernel-image-2.6.8-2-686

add the initrd to lilo.conf and run lilo again before leaving the chroot.

Rescue system after crashing /var

Obtain the skeleton content of the /var directory from a minimum
   working Debian system based on the same or older Debian version, for
   example var.tar.gz, and place it in the root directory of the broken
   system. Then
     # cd /
     # mv var var-old      # if any useful contents are left
     # tar xvzf var.tar.gz # use Woody skeleton file
     # aptitude            # or dselect
