Sorry, it's outside my knowledge envelope. I know the steps do work as I've done them several times in the past. I don't know what the requirements are in terms of compatibility between the linux kernel that's booted and the "broken" system that you chroot to - are they the same architecture you are using ?
Also, I take it you mounted all the directories (/proc, /dev, etc) ?

In the back of my mind is whether the error message is a result of a lower level issue - eg a mismatch between kernel and system.
