Since I don't want to do that, at least not right now, how can I disable the Magna-Steer circuit malfunction warning message in the dash? Can I just plug in a resistor that would simulate the resistance of the coil (about 2 ohms according to what I've heard)?
You shouldn't need to replace the steering rack .... the "coil" is at the base of your steering column ... right ??
That is the Steering Wheel Position Sensor (SWPS) .... it sends a varying set of signals (it should have two "sides" ... or an A and B signal) based on your steering wheel position.
The EBCM goes through a "centering" test (not sure how it's done on the Cadillac) but I suspect that simply putting on some resistors won't fool it. On the othr hand, can't hurt to try ... worst case if you do fool it you will have "regular" power steering as the "varaible" Magnasteer would never get triggered as it would never think you were turning.
The steering column has to be partailly removed to replace the sensor in a Corvette .... you don't have to remove the whole column.
I looked it up for a 1997 DeVille and the sensor is listed at list price $307.72 ..... I found it under .... Steering Column ... Shaft and Internal Components ..... Position Sensor ....
