I once wrote a tiny little program, that used the ioctls defined in
/usr/include/sys/kd.h to switch video modes on my VGA. ISC's 'loadfont -m <mode>'
will do the same. The VGA contains a *lot* of registers though, and I have had
situations, where not even the ioctls would get me a standing picture any more.
Microport's System V/286 used to have a hot key sequence in it's DOS Merge kernel
wich would cycle through all available video modes (it was needed, too).
Sorry I don't have the program here...
