Really strange resolution problems on xorg with a laptop

Has this problem been resolved?
I have the same problem for a similar laptop (HP Pavilion dv5120us).
The X Server 1.4.0 (FreeBSD 6.3-R) works fine, but 1.4.2 (From both 6.4 and 7.1) produce this problem.
My screen is 13.25 inch x 8.25 inch in resolution 1280x800.
The DPI shown in Xorg.0.log is (96, 96), which is correct according to the dpi expression listed below.
Only strange # from the Xorg.0.log is the screen size 310 x 21.
The screen size should be 330 x 301, which is corrected stated in xorg.conf.
I wonder if this is a X Server 1.4.2 bug.
Is anyway to correct this problem? or X 1.4.0 has to be used for this particular laptop till a new X Server released.

Eventually there's a setting in /etc/X11/xorg.conf called
"DisplaySize" that does not match the display size of the
monitor. Take a ruler and check. Then, calculate the dpi
resolution from what the manufacturer says about the amount
of pixels in X and Y (e. g. "1200x800").
physical pixels x
dpi(x) = ---------------------
display width in inch
and
physical pixels y
dpi(y) = ----------------------
display height in inch
The dpi resolution chosen by the X server can be determined
by
% grep DPI /var/log/Xorg.0.log
This should match the reality.
