With all due respect, this is a misunderstanding. There are more tries from the driver to validate a suitable 1680x1050 mode and the 75Hz one I specified explicitely gets removed because of the native resolution being allegedly 1440x900 at max.
I don't want to remove the 75Hz constraint since it's the very point of the whole mess from my part: to get it running at 75Hz.
