That won't help as nouveau (and older UMS nv driver) are not getting I2C right
(they don't know where the right I2C bus is located) to do the EDID transfer.

It's rather a matter of either finding out how nvidia closed driver knows where
to look and replicating that or finding out where the I2C bus is for
nforce/mainboard.
