I think your problem is that you did 'chkconfig --del syslog' - as the 
man page states:

--del name
        The  service  is removed from chkconfig management, and any sym-
        bolic links in /etc/rc[0-6].d which pertain to it are removed.

        Note that future package installs for this service may run  chk-
        config  --add,  which  will re-add such links. To disable a ser-
        vice, run chkconfig name off.

I believe you should have done 'chkconfig syslog off' instead.

We use rsyslog instead of sysklogd and don't get this problem.
