I question whether thats something that belongs anywhere near the
kernel. Ben Pfaff wrote a fine library for vga16 hackery (BOGL) and it
combines very nicely with the fb driver.

You can pull the code out of the old svgalib library. Since its not
doing any card specific stuff the generic vga->text restore ought to do
the right thing.
