I'm getting irritated at Fedora being a bit too bleeding edge for my taste. I have work to do, and can't afford the time I spend farting around with this stuff. Maybe I should join Mr. Raymond over at Ubuntu.
Before that, may I recommend
yum install yum-fedorakmod
yum-fedorakmod.noarch 1.0.2-2.fc6 extras Matched from: yum-fedorakmod Yum plugin to handle fedora kernel modules. Plugin for Yum to handle installation of kmod-foo type of kernel modules, when new kernel versions are installed. kmod-foo kernel modules is described by the Fedora Extras packaging standards. http://linux.duke.edu/yum/download/yum-utils/
basically, it prevents yum from offering new kernels during an update until all the various kmod rpms you have are also available for that kernel.
Running it here with kmod-ntfs and kmod-nvidia and seems to work a treat.
