I am of the same bent. For many security issues that do not mandate a reboot
I just apply the patches following the instructions in the security
32 bit drivers such as NVidia on a desktop box mean you're stuck with i386.
These same drivers usually have problems with PAE kernels as well. In the
server world you are better off not running a PAE kernel. PAE is kludge and
a true 64 bit implementation will give you better performance.
The thing to watch out here would be a controller driver based on a binary
blob. How it was originally built by the mfr can cause trouble in a mix-n-
match environment. I believe most controller drivers these days are OK on 64
bit platforms, it is just a detail to keep an eye out on. But - PAE is
something better done away with and relegated to history. Just my $.02
