Where did you find these? I don't see how they can help. All 132 column
svga & vesa text modes are 16 color (4 bit). These have horizontal
resolution in the 1056-1188 range.

I don't understand. What about 0x16x in 1152X864?

Still need help. Even if I had the VESA specs, I still don't know the
Linux syntax for either grub or lilo. Plus, 132 X 30 is a Trident
