try booting into single mode. you can do this by selecting the kernel line at the grub menu
and editing it - appending the word single or S in the line like:

kernel /vmlinuz-2.6.18-164.el5 ro root=/dev/vg00/lvsys00 rhgb quiet single

then see if it'll boot into single mode.

any chance you are using an nvidia graphics card?
