it's dead code because the current silicon is broken.  i know the code works 
as ive tested it in scenarios where the anomaly isnt triggered, it just cant 
be enabled until fixed hardware is released.  it's much easier to go back and 
fix 1 if statement then have to carry this patch somewhere it can got lost 
and i need to waste time and rewrite it.
