You could do this very easy with a spark ignition car.
You can buy MSD brand RPM activated switches. They are no more than a set of electronics that uses an ignition system signal to figure RPMs, then it turns a relay on or off at depending on what RPM its set for.
Their main use is powering nitrous oxide and fuel solenoids so they can handle any kind of P/S clutch you might want to use.

I will tell you how I would wire it up.
First of all I would have a toggle switch that I could flip on for use in parking lot situations.
Then I would have it wired into the reverse light and brake system so any time I backup or apply the breaks I have P/S.
I would also add a time delay that will power up the clutch for the first minute or so after I turn the key on, that will just to get out of the drive way and on the road.

Then lastly I would also add a little indicator light that will turn on when the P/S clutch circuit goes hot.

I've had an MR2 electric pump (on a manual switch) in my 93 240sx for well over a year now, and swerving works just fine at speed (occurs regularly in LA - people love to try hitting me).

I'm kind of surprised that nobody has mentioned that additional benefit of disabling your PS - good workout! I've definitely gotten stronger as a result

Got a Tracer I'd like to hit 50mpg with; best fe was 42 so I'll have to see what it'll take to bypass the power steering on that one.
Thinking back now, I had a 91 Jetta that had power steering, and a 1.8L with 9.6:1 compression...and I couldn't understand why it would not match or beat my older 84 Jetta's mpg, which also had a 1.8L but with 8.5:1 CR. True the older car was lighter...but it didn't have PS either. I cut the PS belt off the 91 and voila! Matched the older car (another 1 mpg, maybe 1.5. Memory is fuzzy now). Steering felt the same as the older car--same size wheels/tires. 185/60R14.
