from all rules.
+Most NAME= instructions got removed. Kernel 2.6.31 supplies the needed names
+if they are not the default. To support older kernels, the NAME= rules need to
+be added to the compat rules file.

+The udev-acl tool got adopted to changes in ConsoleKit. Version 0.4.11 is
+required now.
