Did you try the more recent versions of exec-shield from Fedora CVS? [1] RedHat continues to maintain the patch, I think it's standard in Fedora, along with SELinux. I didn't try to apply their latest patch for 2.6.26 (revision 1.93 or 1.94) to a Debian kernel source, but it might be a better starting point than the current version in Debian.
