beware that udev rules location have changed!
these were previously in /etc/udev and are now in /lib/udev...

the correct rule should already be present in this file (with MODE=664).

I've recently committed a small improvement to guesstimate runtime.
this will be available in the upcoming 2.6.4.

before adding this new entry, have you tested the shutdown procedure?
