I don't know if any of this will help.. But I am posting it anyway..
I also have a call into Intel's Advanced HPC ( EPSD ) division for more
answers. Maybe they can help, maybe not.

I am being as pro active as I can, hardly understanding what it is
exactly that you need. Outside an exact white paper from Intel.
Anything I can do, I am willing to help move this along. In the mean
time, I am going to try to read the man page that I found for lbflash
since I have it. It's hardly a solution I would want to rely on though.
Thanks,
