Giuseppe, can you send me the EDID block of your monitor?

I'd gladly do it, if I knew how to retrieve it ... because apparently,
get-edid doesn't work, even though both the nv driver for X and
nvidiafb manage to retrieve it.

get-edid uses the BIOS, while the other two talk directly over the I2C
bus.

Try loading i2c-dev (I2C_CHARDEV); With i2cdump[1] you can read the EDID
block, which resides at address 0x50:

i2cdump N 0x50 (where N is the bus number)

If you are unshure about bus number try with all the available
/dev/i2c-* devices (you may want to unload HW monitor drivers first, so
you don't poke at random stuff).
