Comment 2 for bug 530713

There's associated work in gfxboot-theme-ubuntu (see the foundations-lucid-gfxboot-update specification). This is ready to go now; the boot screen looks like http://assets.grimaceworks.com/boot-screen.png, and any key press there takes us through to the main menu as before. If the timeout expires while on that screen, we'll boot through to Evan's ubiquity change.
