Dmesg log

I have an older laptop Toshiba P25-S609 which has NV34 based graphics (NVIDIA
FX5200Go). With 4.2 kernel and lower (and possibly 4.3) native resolution
1440x900 is detected properly. With 4.4 kernel and newer (e.g. Xubuntu 16.04.1
and newer) image on screen is displayed really weird. It is split in 4 parts,
and then it is shown from right to left (inverted). With xrandr --newmode and
cvt 1440 900 I can set the resolution, but then tty is still messed up.
I have tried to get the bug with options drm.debug=0x1e nouveau.debug=debug,
and vbios.rom from /sys/kernel/debug/dri/0/ and it is here:

Here is the image of what it does look like:

Dmesg log is attached below.
