Thank you for the response!
Seeing as this image will be used by the not-so-technical, I would like this to not have choices. I have tried to change the stty version to no avail. I have also tried to use other vga modes. It seems as though rows or columns cannot be added via stty once the image is booted, only removed. Although when they are removed, the screen just blacks out those sections. That won't look right on a full screen CLI app.
