I understand that the .i686 kernels do have PAE enabled, not least
because it’s needed for NX/XD to work.

Hope this helps,

The 'kernel' package does not have PAE enabled.  You need to install the 
kernel-PAE package if you want NX/XD or 4G+ of RAM.

.x86_64 fedora kernels do not usually have this restriction and can use 
all installed ram.  If your CPU is 64-bit capable, that's a good reason 
to run it in 64-bit mode.
