Uh, this doesn't work on an Ultrasparc machine that I've tried it on.  
Have you tried it on anything newer than Sun4m?

A better way to do it for machines with a socketed NVRAM chip is to pull 
the chip, and boot a different model of machine with the chip in - it'll 
recognize that something is wrong and erase the chip for you.

Trying the "hot plug" chip method on Ultrasparcs has only got me busted 
NVRAM chips in the end.
