Aha. 

I was puzzled for a bit about how selinux would come into things on
my system, since I thought during installation I had said not to
enable that, but in fact /etc/selinux/config had SELINUX=enforcing,
and when I changed that to "permissive", hwclock began producing
output when it didn't before.

This also explains the difference in behavior between my FC4 system
and another one to which I have access -- the other system has
SELINUX=disabled.

Perhaps this will be useful information to others on the list.

Fair enough.
