If you dont use any lvm, raid and encrypted devices, you can safely turn 
off all fedora-* services
( Anaconda (F16) finally offers desktop users an easy way to opt out 
from lvm without being partitioning experts )

#cd /lib/systemd/system
#for i in fedora-*; do ln -s /dev/null /etc/systemd/system/$i;done

We throw in udev-settle since it gets pulled in by the storage setup
#ln -s /dev/null /etc/systemd/system/udev-settle.service

If you want speed not eye candy you can disable plymouth

#cd /lib/systemd/system
#for i in plymouth-*; do ln -s /dev/null /etc/systemd/system/$i;done

Then proceeding disabling all the service you dont use.

#for i in service1 service2 service3 etc... ; do systemctl disable $i ;done
