(pardon my ignorance, I do not know this code at all).

Is there a way to make this into a module (like we have done with SIMD 
code), so that it does not have to be hooked so deeply into the format's 
kernel code?  There would still be some interface code (like we have 
with SIMD), but the main functionality is external.

I am sending this offlist, as I do not want to pollute your thread IF 
this is total PEBCAK
