What kind of Ubuntu image are you starting from? I'd try to get the most minimal server install I could to start with. Look up the debootstrap tool to get a minimal ubuntu x86 install created on a disk image (no vga/framebuffer support, no X etc, just a simple serial terminal only system). Then you can use that image with the ARM ubuntu M5 wiki page to cross-reference to get Upstart doing what you want. The wiki page gives instructions to get all the way to a geTTy terminal with multi-user privileges which is useful if you want to run more complex applications. But, you can shortcut this and cause Ubuntu to bring up a bash shell in single-user mode by modifying the /etc/init/rcS.conf script to just execute /bin/bash directly. Give this a try to see if you can get a terminal prompt. Also start reading the Upstart documentation as its quite different than the old SystemV init interface.
