please push testing version of akmod-nvidia-304xx and kmod-nvidia-304xx to stable

[Andre Robatino]

Since the 3.14 kernel was pushed to F20 stable updates yesterday, I
haven't had graphics with my GeForce 6150SE until updating to the
versions that have been sitting in rpmfusion-nonfree-updates-testing.
With the currently stable version, the akmods don't build. _Please_ push
these to stable.
