As a general rule of thumb anything proprietary binary only will be
painful in rawhide. Anything can change through out the dev cycle and
you have to wait for the vendor to catch up. Recently Xorg was bumped
to the latest release requiring a rebuild for the new ABI. You can
either use nouveau and have the latest and greatest or retrieve the
last Xorg server build from koji that supported the ABI required by
the proprietary driver and downgrade to that that exclude the affected
packages from being upgraded.

Fedora doesn't package the NVIDIA driver, I presume you're referring
to the rpmfusion.org one.
