On the contrary, ubuntu-minimal is minimal and doesn't pull in anything
desktop-specific.  It will pull in upstart->mountall->plymouth
->plymouth-theme-ubuntu-text, but that's not a graphical splash screen,
only a text one.

Yeah, I think that's the case; talking with Colin Watson, I understand
that console-common is meant to be removed altogether but hasn't quite
been obsoleted.

Reassigning this to console-tools, which seems to be the primary
culprit.

Title:
  plymouth always shows a splash screen regardless of whether 'splash'
  is on the command line

Status in “console-common” package in Ubuntu:

Bug description:
  Binary package hint: plymouth

  On Ubuntu Server 10.04:  Even when I don't have 'splash' as a kernel
  parameter, plymouth still shows a splash screen (which seems to be
  done by  /usr/share/initramfs-tools/scripts/init-top/plymouth).  On
  its own, this is a minor niggle.  However, it has a more serious
  knock-on effect if the system is configured with a default locale
  which uses UTF-8.  In that case, much later in the boot process,
  /etc/rcS.d/S05keymap.sh tries, via the unicode_start program, to run
  the vt-is-UTF8 command, which hangs if there is a splash screen
  present (this part is arguably a bug in console-tools).

  The combination of these two bugs, one in this package and one in
  console-tools, is that the console of the machine never produces a
  getty, because the rc script never completes.  If you don't have a
  network connection working yet, you're reduced to having to use
  init=/bin/sh to get a prompt, because the same situation prevents you
  getting into single user mode too.
