Meanwhile I doubt this explanation. Here's what fbset has to say:

$ fbset -fb /dev/fb1 --show

mode "1680x1050-60"
    # D: 135.501 MHz, H: 65.396 kHz, V: 59.997 Hz
    geometry 1680 1050 1680 1050 32
    timings 7380 32 224 32 4 136 4
    rgba 8/16,8/8,8/0,8/24
endmode

So, even fbset thinks it's 1680x1050. But where does the distortion come 
from???

Can you try setting vxres for second head from 1680 to 1696, or 1728? 
Maybe X look at vxres and not at framebuffer line length (what fbset -i 
reports for line length?)

These days at least the X server in Debian looks correctly at the frame buffer
line length, else it wouldn't work on PS3 with non-fullscreen modes.
