You've actually specified "noddc" so it's not going to read the DDC

Specifying a modeline with the i810 driver without a matching BIOS
modeline is fruitless.

You should check out the program i915resolution to override one of your
existing modes to the 1400x1050 mode. Given that your BIOS manufacturer
neglected to add a 1400x1050 mode into the BIOS - this is currently your
best route - unless you want to build the "modesetting" branch from git
which programs the modes directly.

Hope that helps,
