If you can't boot, you can bootsrap from a live CD, and change your /etc/inittab (to init 3), and then boot from the kernel of interst.  Since this is a bit of a pain, I've also changed /boot/grub/grub.conf (commenting out hiddenmenu).

      You can set the runlevel at the grub screen.  I think you can hit 
escape to get rid of the splash screen, I always comment it out in 
grub.conf, so cant be sure of this.  Then, press the letter A, hit space 
and the number 3.  Saves a visit to the live CD.

           HTH.
