rm /Volumes/<HD-NAME>/System/Library/Extensions.*

Once you have done this you should try to boot on the actual machine
and not another machine.

Can you boot from the Install DVD on the machine with the problem?

Removing all of the kernel extensions seems like a rather radical thing...yes, I can boot from the install DVD.

Try reading it again or put your glasses on, it deletes 2 files and only 2 files.

try:
ls -lsa /Volumes/<HD-NAME>/System/Library/Extensions.*
