Instead of landing these coefficients like that, I would really like if 
you could dump pfuse and check if you find these coefficients there. 
What could be done also is to re-do the work you did to find out those 
coefficients on a GPU where your coefficients are not really good and 
find out what values would have needed and then compare pfuse with the 
original card.

If this is to be considered a long task, then I am OK landing those 
coefficients, but I would really appreciate if you could at least have a 
quick look at pfuse :)
