Correct. The oops/panic occurs immediately after pushing the programmer switch.

I do not belive so. There is a way to trigger an NMI in OS X via setting 
boot-args="debug=0x4" in the nvram. If this is set, the power button becomes a 
programmer switch. Apple removed the programmers switch after the PowerMac G4.
It looks something like:
