Problem is that KVM switches emulate monitor keyboard and mouse to the
computers. This is because default BIOS settings prevent the computer
from booting if the keyboard/monitor aren't present -- and ps/2 mouse
connectors are generally sucky and don't accept a mouse if it was
plugged in after the computer booted (could be a winderz problem,
actually...).

Anyway, your KVM switch tells your machine that the monitor resolution
is 1400x1050 and F11 happily obeys (thinking the resolution info is real).

Setting it to 1680x1050 (only, no other resolutions!) in xorg.conf
should normally make it work. You'll need to restart X -- and for that,
you may need to reboot the machine. If you can't reboot, you can change
runlevel to 3 and then back to 5:
# init 3
[... wait a little for console to settle down ...]
# init 5
