>From your own log:

[    35.477] (**) intel(0): Display dimensions: (410, 310) mm
[    35.477] (**) intel(0): DPI set to (86, 86)
...
[    35.914] (II) intel(0): Setting screen physical size to 370 x 277

Which means:

$ qalc '1400 / (370 mm to inch)'
1400 / (370 * millimeter) = approx. 96.108108 / in
$ qalc '1050 / (277 mm to inch)'
1050 / (277 * millimeter) = approx. 96.281588 / in
 
Wanna' bet 'xdpyinfo | grep reso' on your machine shows

  resolution:    96x96 dots per inch

?

P.S. I get the same "resizing" to 96 dpi with latest Xorg + nouveau from Debian 
unstable, so this is not limited to intel
