I'm still not quite sure exactly what you'd like to achieve and why
XFree86 was closer to it than X.Org, but my best guess so far is that
it's because X.Org now actually knows a 1680x1050 mode for the CRT,
whereas XFree86 didn't. If you change the SubSection "Display" of
"Screen1" to something like
Modes "1400x1050" # change to the mode you want on the CRT
Virtual 1680 1050
Does that come closer to what you want? If not, please provide an
XFree86 logfile for comparison.
