Just built ISO with the according configuration.
The ISO as well the full grub directory can be found at:

  http://amd64.grml.org/bug_605567/

[kvm|qemu] -hda ./grml-small-sid_2010.12.20.iso triggers the problem
for me (notice that isolinux will come up if using -cdrom instead of
-hda, jfyi).

If you need anything else please let me know.
