With newer kernels (3.13+), the output is a little different and you'll also
see a 'c' line which indicates the current speed. (I believe with pre-3.13 you
also saw a 'c' line but it was probably empty for Kepler cards.) I'm not sure
how accurate those readouts are for kepler on pre-3.13.

Like I said, nouveau can't change clock frequencies, so it'll be in whatever
level the vbios leaves it in. (Which might not be one of the listed levels at
all!) Often, for Fermi and newer, it's the lowest or second-lowest one.
