Description of problem:
Anaconda installs kernel-PAE instead of kernel to a system with 512 MB RAM.
Version-Release number of selected component (if applicable):
I'm attaching dmesg from the system for both kernel and kernel-PAE as well as anaconda.log.

Happens also with a 1GB laptop, attaching PAE/non-PAE dmesg outputs and anaconda.log.

Laptop anaconda log
Also have PAE-kernel installed on 1Gb ram laptop with F11.
Dunno why PAE was used...
This is intentional, see http://fedoraproject.org/wiki/Features/ArchitectureSupport
The short is that we cut down on the number of shipped kernels by having all i686 hardware which is PAE capable use the PAE kernel rather than having separate kernels. The PAE kernel has performance advantages for such hardware as you can use the hardware nx support rather than requiring the emulated version in the kernel
