I just went through a similar experience with an Acer 22" widescreen monitor
and an Intel video chipset.

After fiddling around with it for most of a day and trying, finding and
calculating modelines to no end, I finally realized that the monitor was
actually reporting what it wants for a modeline.

Check the EDID information reported in /var/log/Xorg.0.log

Here is the relevant section of the  Xorg.0.log with my Acer AL2223W monitor:

QUOTE:
(II) I810(0): Supported additional Video Mode:
(II) I810(0): clock: 149.0 MHz   Image Size:  474 x 296 mm
(II) I810(0): h_active: 1680  h_sync: 1784  h_sync_end 1960 h_blank_end 2240 h_b
order: 0
(II) I810(0): v_active: 1050  v_sync: 1053  v_sync_end 1059 v_blanking: 1089 v_b
order: 0
(II) I810(0): Ranges: V min: 56  V max: 76 Hz, H min: 31  H max: 82 kHz, PixCloc
k max 150 MHz
(II) I810(0): Monitor name: AL2223W
(II) I810(0):  ACER
END OF QUOTE

Now here is my modeline:

 Modeline "1680x1050" 149 1680 1784 1960 2240 1050 1053 1059 1089

Note that it consists of the mode name, then the clock rate, then the four
numbers from the h_ line, then the four numbers from the v_line, in order.

I put this modeline as the last line in the Monitor section
in /etc/X11/xorg.conf

I added "1680x1050" to the Modes line of the Screen section
in /etc/X11/xorg.conf.

I hope this helps get you on the right track.
