This drivers creates I2C buses which are needed for accessing the DDC (I2C) bus present on all Matroxes, an I2C bus which interconnects Matrox optional devices, like MGA-TVO on G200 and G400, and the secondary head DDC bus, present on G400 only.

You can say Y or M here if you want to experiment with monitor detection code. You must say Y or M here if you want to use either second head of G400 or MGA-TVO on G200 or G400.
