Thank you for your findings. Unfortunately it still doesn't work 
with the same issue: will not find/mount the root device.

After booting I can't even mount /dev/ram0 manually at the busybox

I've grown a bit tired by this already. Before I will try your and 
Neil's suggestions I will test my luck with the Sysrescuecd iso. 
It seems that more people are interested in this and are reporting 
success.
