The problem is that SuSE isn't consistent in how it wants /etc/sudoers treated. Our default for all other OSes is 440. We don't run into problems on our installs with setting it to 640, so something is different with your install that is causing that to be problematic. In fact in our installs, setting it to 440 is what causes problems on SuSE.
