Some people use 66-cells braille devices for reading the console, and hence
would like to reduce the width of the screen by using:
stty cols 66
However, the vga text console doesn't behave correctly: the 14 first
characters of the second line are put on the right of the first line and so
forth.
Here is a patch to correct that. It corrects the disp_end and offset
registers of the vga board on console resize and console switch.
On usual screens, you then correctly get a right and/or bottom blank
margin. On some laptop panels, the output is resized so that text actually
gets magnified, which can be great for some people (see
