the 64bit ubuntu kernels have Non-eXecutable (NX) memory protection enabled by default. on 32bit only the PAE kernel has hardware NX, whereas the normal 32bit kernel has emulated NX.
see http://www.ubuntu.com/getubuntu/releasenotes/910overview and http://wiki.ubuntu.com/Security/Features#Non-Exec Memory
you should probably read through the topics at https://help.ubuntu.com/community/Security
