As Dave Jones mentioned, use "chkconfig" or the gui to disable services 
instead of messing with the symlinks by hand.

Here are the services that I run on my desktop FC3 system. Perfectly 
functional, except that I have scripts that I run myself that replace 
the normal cron scripts.

syslog
network
cups
xfs
iptables
haldaemon
messagebus

Boots from power off to level 3 login prompt in 41 seconds (including 
the grub timeout).
