These display mode configurations are a combination of modes made by
Sony[1] and modes from the PlayStation 3 frame buffer driver (ps3fb.c).

The VESA modes are designed to work with the synch-on-green (SOG) VGA
cable that Sony distributed with the Linux kit for the PlayStation 2.
Modern computer displays typically do not support synch-on-green, so
an adapter is most likely necessary for these modes.
