Using the equvalient syslinux.cfg entry, I was able to boot grml iso from HD
using grml-small from USB, but there is a problem,

The problem may related to this (unable to load modules). Thy symptom is that
the ifconfig -a only shows lo device, not eth0. If I specified 'ifup eth0', the
respond was no such device or similar. Duplicated the result each time when
tested.

Booting grml-small or grml directly won't have such problem. eth0 works fine. 

Test environment: grml 0.9/grml-small 0.3
