 Forwarding this bug from a Ubuntu customer.

 Problem:  Incorrect resolution detection on CX700 chipset.

 This is similar to bug #297, however the solution to that bug did not fix
 it here, as the issue persists, having tested svn 712, 741, and 758.

 The inbuilt 800x600 display of one of an LEX Panel PC gets a distorted
 picture. It seems like they have lost vertical, possibly also horizontal
 sync. To ensure that this is not a hardware problem, they ran Fedora Core
 8 on the PC in question and the display is perfect. They have also tried
 to connect an external LCD screen, whilst running Ubuntu 9.04, which
 yields a perfect picture on the external screen (800x600).

 Here is an excerpt from the customer comment:

 So far no difference, here's the install log:

 sudo dpkg -i xserver-xorg-video-openchrome_0.2.903+svn741-1_i386.deb

 This doesn't appear to have changed.

 Looking at the log file they are getting the same error for every
 resolution tried:

 (II) CHROME(0): Not using default mode "800x600" (hsync out of range)
 (II) CHROME(0): Not using default mode "400x300" (bad mode
 clock/interlace/doublescan)
 (II) CHROME(0): ViaValidMode: Validating 800x600 (49500)

 The customer has tested xserver-xorg-video-openchrome
 1:0.2.903+svn758-0ubuntu1 from the karmic repositories and reports that
 this package has not fixed his issue.
