Hello. GRUB2 contains executable stacks. Usually these are not needed
and can be easily fixed.
betelgeuse@pena ~/checkouts/grub2 $ scanelf -qeR .
RWX --- --- ./grub-setup
!WX --- --- ./pxeboot_img-boot_i386_pc_pxeboot.o
RWX --- --- ./grub-emu
!WX --- --- ./kernel_img-kern_i386_pc_startup.o
RWX --- --- ./grub-probefs
!WX --- --- ./boot_img-boot_i386_pc_boot.o
RWX --- RWX ./kernel.exec
--- --- RWX ./diskboot.exec
!WX --- --- ./normal_mod-normal_i386_setjmp.o
!WX --- --- ./diskboot_img-boot_i386_pc_diskboot.o
--- --- RWX ./pxeboot.exec
--- --- RWX ./boot.exec

This document is very helpful in fixing this problem.

Petteri
