I wish NVIDIA would support yum. NVidia, are you listening? Keeping the kernel updated with the real nvidia driver is a pain, but needed is you run the real nvidia driver (like we do). For those not experienced with RHEL and nvidia kernel modules, when you install a new kernel, you have to run the nvidia installer after the system boots under the new kernel to build the nvidia module for that kernel. Then a reboot gets it all working again. Imagine doing that for 25 engineering workstations in a dept, and you'll get the idea. Yum works great if you can live with the default 'nv' driver.

Right, although distributions like RHEL do a good job of keeping the kernel unchanged from an API perspective within a given release.
