How can I start System Preferences from the command line?

Question

Hello All,
I have an issue I'm not quite sure how to solve. I have been tasked within my business environment  with tightening security on a Mac Leopard system and I've been granted Admin Rights to do this on a temporary basis.
The problem is as follows:
1) The original Sys Admin that set up this system is gone, no longer available.
2) He was a Dvorak Keyboard fan and set up the system for a Dvorak Keyboard.
3) The system actually has a standard Apple keyboard and is marked accordingly, i.e., qwerty (Most Users in the building have stopped using this system altogether - a terrible waste of a good system - even though some of their apps can be run normally (US style qwerty settings). The command line is useless, as is texteditor.app and a few others unless you know Dvorak layout)
5) When I open System Preferences, the Dvorak keyboard checkbox is grayed out and I cannot change it. There is no lock at the bottom of that particular screen for me to unlock.
6) Even though I select the US Keyboard at Login, and some apps work accordingly (like MatLab for example) the terminal is borderline useless. I spent over 2 hrs yesterday doing what should have been able to be done in about 30 minutes. I estimate a frustrating and mistake prone additional 8 to 10 hours to do what is normally a a 4 hour job at the command-line.
7) I do not have the time or desire to re-mark all the keys on the keyboard, particularly since it is not my call to do so, nor do I have the time to re-learn Dvorak touch-typing, and finally I do not want to re-load the entire system. I just want to change the darn keyboard to a standard qwerty keyboard that is somewhat useful in a terminal environment with vi, command line, etc. It's either that or I go mildly insane
This is frustrating as all get-out. The new Admin logged in and was able to uncheck his Dvorak settings (he is not a UNIX guy, nor is he comfortable om Macs), and we were hoping this was a system wide setting, but No. We re-booted the system, I logged in, still Dvorak, and the checkbox was still grayed out.
So I figure, short of re-loading the entre system and all the applications necesary, I can either start the Systems Preferences GUI using sudo and hopefully that will change system-wide settings, or I can delete the .AppleSetupDone file and resetup the system (if the keyboard settings are part of the setup) without spending a couple of days reloading everything and re-setting up users, networks, etc.
Needless to say, I am hoping for the easiest and quickest solution to this extremely frustrating and  aggravating problem.
Thanks.

For my situation the following C# code does the job:
    Process.Start(
       @"c:\Program Files\National Instruments\CVI71\cvi.exe",
       @"c:\temp\experiment.c" );
The file must already exist.
