Binary package hint: initramfs-tools

Solved the problem with

sudo mkdir /lib/modules/2.6.32-22-generic
and
sudo touch /boot/System.map-2.6.32-22-generic

before purging again, and finally deleting initrd and System.map under /boot manually, and also the corresponding modules directory under /lib/modules/.
