Old description:
This is a trick used in the Clover bootloader to get native video modes
from VESA.
The idea is to patch the VESA BIOS (which is shadowed in RAM) and replace
the video mode tables with the EDID data.
This gets native video mode on ATI, NVidia and Intel cards, without the
need to write an actual driver. Their Vesa BIOS is smart enough to accept
any resolution in the table.
