it looks like one of the recent updates will sometimes chmod /dev/null to 600. out of 20 machines i've updated, 3 of them had the odd /dev/null perms afterwards. i haven't tried to identify what it doing it yet, but wanted to give a heads up to others that might start seeing weird behavior.
Look in /etc/udev/rules.d/50-udev.rules. My copy has the line:
KERNEL=="null", MODE="0666", OPTIONS="last_rule"
You haven't managed to mess with this rule?
