I know we used to put the signal handler trampoline on the stack, but these days that should all be handled with the magic executable syscall page, so _normally_ I don't think an old application should even really care. In fact, it would be interesting to just hear somebody running an older distribution with a new CPU and a new kernel, and see just how many programs need to be marked non-NX in "normal running".
