Hi Antonino,
I am having the following issues on my Dell Inspiron 8100. They are not new but I just got around to report them.
With CONFIG_FB_NVIDIA_I2C I get 1600x1200 resolution but pixels "swarming" and it is unuseable. There are following messages in dmesg (note complaints from i2c):

If I disable CONFIG_FB_NVIDIA_I2C and enable CONFIG_FIRMWARE_EDID then it looks like I have a virtual screen with large font extending past physical. If I do:
fbset 1024x768-60 fbset 1600x1200-60
everything is back to normal.
And below a cosmetic patch for you...
Thank you.
