Yes, but if I remember correctly again, the real values are not printed out in
kernel <= 3.13 if they were limited. I think I've seen a patch from Alex or
Christian about that so we can have the real values in kernel 3.14.
Otherwise, I could provide you a patch of mine that gives the real values used
(it's printed as a warning saying the values have been limited to X). I'm
experiencing similar problems with my HD6950, that's why I've been digging on
my side.
