  Before I start, I'll restate my opinion that going for a text-mode
  program will probably end up being harder in the long run than going
  for a PM program.

  With a PM program displaying teletext characters would simply be a
  matter of whipping up a custom font using the font editor, and writing
  the display logic (which will at most devolve into a succession of
  GpiCharStrAt calls).

  With a text-mode program you'll have to set up a custom VGA text-mode
  character set (VioSetFont is not the most heavily documented call in
  the VIO subsystem), and *require* full-screen, since custom character
  sets (obviously) will not operate in a window (i.e. when the display
  is in graphics mode).

  Wrong way around.  All of the VIO calls are available to a full-screen
  text-mode program.  Only a subset are available to windowable
  text-mode programs.  The reason being (of course) that the calls to
  access the physical text-mode video buffer directly are prohibited to
  windowable text-mode programs.
