The quickstart document cited in the article says:

- make sure you have a CPU that has the NX feature. Such CPUs are:
  all 64-bit variants of AMD (Athlon64, Opteron), future CPUs of
  Intel, Transmeta and VIA. (NOTE: 64-bit x86_64 kernels already
  make use of the 64-bit variant of the NX feature - this patch
  is only meant for 32-bit x86 kernels and distributions.)

So you do have to have a compatible processor. This change adds protection when you are running a 32-bit kernel.
