Check /boot/grub/menu.lst, sometimes the line with the initrd.img is missing. You can edit it by booting with knoppix, mount the partition and edit it. This sometoimes is caused by the grub-install script. Ifyou need a new initrd, do this in /boot/grub/: i.e. mkisofs -o initrd.img-2.6.18-4-amd64.img /lib/modules/2.6.18-4-amd64 > I try with a 2.6.20 kernel, take the 2.6.19 config found in the Knoppix > install and a make oldconfig.
