Hello,

May I risk a platitude? The configuration is strictly depending on the 
use of your PC.

I try a few comments here after:

acpi :  keep it Advanced energy management keep it
anacron: tasks scheduler (do you schedule services to be executed on your system?)
atd    : tasks scheduler (do you schedule services to be executed on your system?)
auditd :  Linux Auditing System Daemon, which collects security related events in a dedicated audit log. If this daemon is turned off, audit events will be sent to syslog. Requested by SELinux.  Do you configure SELinux?
autofs : keep it. To automatically mount devices / file systems
avahi-daemon : This is a daemon which runs on client machines to perform Zeroconf service discovery on a network. avahi-daemon must be running on systems that use Avahi for service discovery. Avahi-daemon should not be running otherwise.
cpuspeed: keep it (This script enables/disables processor frequency scaling support, either using the cpuspeed daemon or in-kernel frequency scaling support)
crond : tasks scheduler (do you plan services to be executed?)
cups : print management
firdtboot: to be disabled (is it the first run of your system?)
gpm : to use cut / paste
haldaemon : keep it
hplip : is a HP printer connected to your PC or network?
libasm :
ip6tables : firewall, keep it
iptables : firewall, keep it
irqbalance : The irqbalance daemon will distribute interrupts across the cpus on a multiprocessor system with the purpose of spreading the load (Intel Core 2 Duo, AMD X2). No impact on single processor
isdn : to be disabled (your access relies on an Adsl connexion)
jexec : keep it
kudzu : do you frequently change your configuration? If not, disable it
lm_sensors : to capture various information from hardware probes
lvm2-monitor : did you configure a Logical Volume on your system?
mctrans : requested bu SELinux
mdmonitor :  mdmonitor service checks the status of all software RAID arrays on the system. Does your system comprise Raid disks?
messagebus : keep it
micrrocode_ctl : keep it
netfs : do you Mount and unmount network filesystems?
nfslock: Mount and unmount network filesystems.
pcsd : to support smartcard.
portmap : no more use until NFS V4
rawdevices :
readahead_early: keep it  (to improve boot performance)
readahead_later : keep it  (to improve boot performance)
restorecond : requested by SELinux
rpcgssd :requested by Network File System
rpcidmap : requested by Network File System
sendmail : do you manage a mail server?
smartd : disks supervision
sshd : do you need ssh connection to your system?
syslog : keep it
yum : to automate the updates
yum-updatesd : to automate the updates


I hope it will help you tune your system ...

Best regards,
