Are you using a initramfs? who mounts the required file system for
upstart to work?

try replacing upstart by a shell script and once you have a shell
exec /sbin/init with extra debugging.

Double check your kernel configuration to have networking and sockets enabled.

Your hardware might also be different causing a different events to happen
in a different order (for example a tmpfs to be mounted over the place
where upstart has it's unix socket waiting).
