Thanks for pointing that out! I'll look into this ASAP.

Duped these two to #727696.

This seems to be something else. The reporter says the permissions are

  crw-rw----+ 1 root root 21, 0 2010-09-28 18:59 /dev/sg0

Which already seems correct (the '+' is the automatic ACL). So I
didn't dupe that one.
