FYI: Let me add a point to this,

If you have GRUB installed, you can add the runlevel number to the end
as a kernel parameter.

Look in /boot/grub/grub.conf for:
   kernel /boot/vmlinuz-2.6.17-1.2139_FC4 ro root=LABEL=/ rhgb quiet
Change this to:
   kernel /boot/vmlinuz-2.6.17-1.2139_FC4 ro root=LABEL=/ rhgb quiet 1
