My collection of computers includes a very nice Thinkpad T41p with a 1.7GHz
Pentium-M CPU which lacks PAE. I don't use it much at the moment as it has a
defective LCD screen and a laptop with an external display isn't as useful.
But it would be good to have NX protection on such systems.
Such protection is useful for desktop systems as they typically manipulate a
lot of data from untrusted sources (such as videos from the net). It's also
useful for low end servers which tend to not be updated very often.
It is possible to have a non-executable stack on systems without PAE, there
are several implementations of this. But Linus apparently never liked any of
the patches.
