[ubuntu-hardened] NX bit and generic-pae kernel.

[Daniel Curtis]

Hi

I would like to know if I should install a generic-pae kernel
when my computer support NX bit? For now, I'm using non-pae
generic kernel and NX is not enabled. My computer is an
Intel(R) Celeron(R) CPU E3200  @ 2.40GHz  (dual core).

Do I have to install only linux-image-3.2.0-39-generic-pae package and
NX protection will be activated during system start? Here's the information
from e.g. '/var/log/dmesg' file about NX bit;

*Notice: NX (Execute Disable) protection cannot be enabled in hardware:
non-PAE kernel!
NX (Execute Disable) protection: approximated by x86 segment limits*

Cheers.
