It's an interaction between the KDE Display Manager (kdm) and the X server 
that is creating your problem.  I had a similar problem with a ViewSonic 
VP201m when I upgraded to SuSE 9.3.

There appears to be an assumption that when probed the monitor will return 
the maximum resolution that it is capable of supporting.  The VP201m only 
returned the current geometry.

In the 'Section "Screen"' of the /etc/X11/xorg.conf file, I had to make 
sure that the only 'Modes' lines present were for the screen geometry that 
I wanted to use.  In the 'Section "Modes"', I had to remove all 'Modeline' 
statements except the one that I wanted to use.

As I had an nVidia graphics adapter, I found that I needed to replace the 
Xorg driver with one from nVidia.
