Dag,
I think to do what you want, you would need the source code for the drivers; our drivers don't currently support that. There are two options:
1. License the driver code for LoCe and modify the display driver yourself.
2. Contract with LogicPD to modify the display driver for you; you will receive the source code only for the modified driver.
For more information, please contact Logic PD sales:

Another possible option would be to create an application that ran under LoLo, confirmed which setting to use with the user, and then returned a value for use in a script that executed the appropriate command.
