You'd think so, but time tested method has taught me it doesn't matter  
what instantaneous method you use, there's no way you can actually  
clear it properly if it's corrupt. IIRC the CUDA doesn't reset  
everything in the PRAM anyway. I've had machines die so far they  
wouldn't even chime on power-on and nothing, including CUDA resetting  
worked. Removing all power sources effectively leads to the computer  
forgetting it ever existed, which is about the best factory reset  
you're ever gonna get!
