Re: No nvidia for -3.3.1-2.fc16.x86_64
You can install the akmod-nvidia package and it should build the kmod. Might need to reboot twice.
However, I was having a lot of problems with segfaults lately so I completely removed the nvidia driver packages and I am currently running the nouveau package, which is working fine for my purposes and seems to not have those problems.
[You may have to not only erase the *nvidia* packages but also comment out the nouveau blacklist line in /etc/modprobe.d/blacklist.conf if you had the proprietary drivers installed.]
