Make the first instruction in your init be a JMP to the third instruction.
Make the second instruction be a JMP to code that will set up your globals
for you(these globals will probably be imbedded in your patch).

Now when you change the settings in the cdev, load in your init resource,
and jump to 2(A0) where A0 is the begining of the code.

Or if you can wait until reboot before changing things around, then just
store that info in a resource and read it on the next reboot.
