This is definitely the mode we want to use.
$ xrandr --verbose --output DVI-D_1 --mode 1920x1200 screen 0: 1920x1200 506x316 mm 96.28dpi crtc 1: 1920x1200 60.0 +0+0 "DVI-D_1"
!@#$ randr doesn't print out WHICH mode they are actually setting :-(
OTOH - can you verify your Xserver version? There was one infamous sync polarity bug. $ rpm -q xorg-x11-server-Xorg xorg-x11-server-Xorg-1.3.0.0-42.fc8
Uh-oh. Yes, this version is probably still affected. You could of course try a newer Xserver version.

Probably xrandr and/or the Xserver is too old. But that is just a wild guess...

Hm. This actually looks good, though you could compare the output to just before trying the xrandr --addmode's.
and then setting
xrandr --verbose --output DVI-D_1 1920x1200_a
or 1920x1200_b, respectively.
$ xrandr --verbose --output DVI-D_1 --mode 1920x1200_a xrandr: cannot find mode 1920x1200_a
You can try xrandr --verbose --output DVI-D_1 --mode 0x62 instead.
Obviously from earlier error.
Not really obviously ;)
