PIO_FONTRESET ioctl which is old and the flag KD_FONT_OP_SET_DEFAULT.
I have to look at the setfont code to see if it sets this flag. I bet 
it doesn't. I don't see a flag to tell setfont to use this font as the 
default font for all terminals :-( The good news is you can tell which tty 
to change the fonts on (-c /dev/ttyX). So setfont has the idea of setting
a single tty but due to a bug in the console layer it set all terminals. 
I guess we need to update setfont for setting all terminals.

Ug!!!! I have cursor_shape in struct display for this reason. Will have to 
trace to find the problem.

   Your right. I realize my logic error. I was literally thinking too black 
and white. In the case of a cursor that is a white thin line at the bottom 
and a grey background. That is whole cursor image!! The mask should be
the font image to be drawn. 
   You can think of it as the cursor being a big grey cookie with white 
frosting decoration on the bottom. Then I come with my font shape cookie 
cutter and cut it out.

Line 420 in vt_ioctl.c.

I'm not sure I follow you.

What I do in that echo is set softcursor. It was software cursor even
on plain vga. Boot into 2.4 to see how it should look like. It works
even in vga text modes. It is different from softcursor later
introduced by fbcon. Documentation/VGA-softcursor.txt describes it.
