Looks like you are using LZMA compression (which is the default in
current squashfs version) whereas the grml-small kernel does not
(yet) support LZMA. So either use the current full 2.6.23-grml
kernel or just disable LZMA in grml-live using:

,---- [ http://grml.org/grml-live/ ]
| -z
| Use ZLIB instead of LZMA compression in mksquashfs part of the build
| process.
`----

or via setting SQUASHFS_OPTIONS="-nolzma" in /etc/grml/grml-live.conf
Make sure to use grml-live version 0.0.13.
