Unfortunately, this is true only up to EGA graphics resolution.
After that, the AT&T/Intel/SCO/Microsoft/ISC/whatever consortium
took completely different paths to VGA and super VGA graphics
resolutions.  Unless WP has built in knowledge of the mode
assignments which each UNIX variant uses for VGA graphics, it
won't fly using the kernel calls to set the graphics mode.

There are other methods to achieve what is needed, but the
kernel calls have grown warts.
