No, let me be a little more accurate in what I am saying.

First of all explore your BIOS settings to see if there is an option
to enable NX. There should be and, if not, it is likely to be a lack
of good will by the manufacturers for not providing this in the first
place. It happens especially in cheap computers such as my Acer One
netbook.

It means there is a fault in the BIOS set up. The manufacturers have
or should have  written new BIOS code to correct this in an update. NX
is not enabled until after the update has been made.

BE WARNED. A BIOS UPDATE CAN TURN YOUR COMPUTER INTO A DOOR STOP IF IT
GOES BADLY WRONG. THE COMPUTER MAY NEVER WORK AGAIN.

NX is a security feature which ought to be enabled but you may well be
able to live without  it.

You can still try installing a PAE kernel but I don't understand how
this would help as PAE means physical address extension. PAE code
enables 32 bit computers to use more that 4GB memory. As you have 1GB
then I don't see that you need it.
