Well, anything is possible.  It just might take alot of time.  I
personally have never tired Intrepid -> Jaunty (which wasn't ever really
supported) -> Karmic -> Lucid on ec2.

I don't know why you wouldn't be getting any console output when you launc
the instance, but I would suspect that something in /etc/fstab isn't
right.  Getting console output is really going to be required for any idea
of what might be going wrong.  I would also suggest jumping to a karmic
kernel if possible, skipping the jaunty one.

What you're asking *can* be done... your approach is sound, but its just
undocumented waters on ec2 and that old.  once you were to karmic, i would
not expect too many hurdles.
