[PC-BSD Support] More screen resolutions

Hello all,

first, I'm new to PC-BSD but have some FreeBSD (command line), Mac OS  
X and GNOME-Ubuntu experience.

Shortly after installation I was asked to set my preferred screen  
resolution, which offered me a long list, including the correct  
1152x864. However, this setting was ignored, the screen is now at  
1024x768. KDE's screen resolution list is a lot shorter, maxing out  
at 1024x768.

 From previous experience I've learned there's some protocol between  
the graphics card and the monitor and my monitor is a bit  
conservative and reports a maximum resolution of 1024x768. However,  
one can add additional resolutions with xrandr[1]:

xrandr --newmode "1152x864 LG" 108.00  1152 1216 1344 1600  864 865  
868 900 +hsync +vsync
xrandr --addmode VGA "1152x864 LG"

These commands succeed and the new resolution shows up in the KDE  
system preferences panel. Too bad, selecting the new resolution has  
no effect at all, the selection menu just hops back.

So my question is: How would I make the system preferences panel to  
actually accept this resolution and/or how would I make KDE to not  
fiddle with monitor resolutions at all, accepting what I've choosen  
at install time?

"PowerStrip" under Windows XP.
