It's saying that you have nvidia driver 195, but it's looking for driver 260 (which is current). nv is the OLD open source (non accelerated) nvidia driver. It has mostly been replaced with neoveou (I probably spelled that wrong) but as you're running the older 13, yes, you'd probably have nv still.
In order to get nv to work, you'd have to remove the module blacklisting of it and set your xorg.conf to use it again. Just changing it to nv will not fix as the nvidia package blacklists this driver if I remember correctly.
It would be best if you could get the correct nvidia proprietary driver installed as it has 2d/3d acceleration. I'm not certain why it's seeing 2 different driver version, I'm thinking it partially upgraded the nvidia package but didn't upgrade everything.
What repository did you get this from since you installed via yum? rpmfusion I'm guessing, but just want to make sure.
