i would recommend using aux/realemu. it provides a measure of safety
when doing mode setting. it could be that the vesa bios does go off
into the woods when it detects a 16:9 monitor. the vesa bios has access
to this information through the edid sideband communication, which
is available on almost every video interconnect, including vga.
