I actually do have monitor section. The xorg.conf there is for modesetting
branch, and AFAIK the monitor section does not matter there, so I
intentionally removed it. Here's the link for my regular xorg.conf.
As I said. I can set 1024x768, even 1280x1024. But 1680x1050 on
non-modesetting emits clocks or frequencies that monitor can't handle. I use
gtf to generate modelines.
I also looked a bit closer on the log.

The SAREA width is two times larger than needed (1680 * 2) and that causes
output cropping. I don't know where this and the blanks on the sides come
