After playing around, I see that cpuspeed is not started at boot time, yet it is set to do so (on run levels 3, 4 & 5). There's no error message, it's just ignored. But if I telinit between run levels, it does start up. Darned if I can see what the problem is. The init scripts appear to have the right permissions and contexts, there are start scripts in the appropriate rcX.d directories. -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.)
