Comment 6 for bug 244838

/usr/sbin/laptop_mode actually checks /etc/default/laptop_mode for ENABLE_LAPTOP_MODE, so that would be the easy, less intrusive way to migrate it, without touching /etc/laptop-mode/laptop-mode.conf at all. On a default install this file doesn't exist until now (only on powerpc to disable it). So in what I wrote in the previous comment, replace latop-mode.conf with /etc/default/laptop-mode.
