This is the culprit: gfx_mode_select() is changing the text drawing mode,
and the details of what you do with it will affect which mode you are left
in. Before calling textout(), you need to reset the mode by calling
text_mode(0), text_mode(-1), or whatever...

In this case, yes, but in general it's a lot more use if you can isolate a
_compilable_ section of code that demonstrates problems: it's a lot easier
to figure out what the problem is if I can actually build and run the
thing!
