No idea about the "required sysfs object not found", what is
the exact error message and when/where do you see it?

As a starting point, which Grml version + flavour did you try?

Also, which kernel modules are loaded when Ubuntu is running, vs
what is running (and possibly missing) compared to when running Grml?
