I'm not sure if the problem was the difference in the /boot/grub/grub.conf file versus the /etc/grub.conf file.

Select the oldest kernel and boot it. That one SHOULD work. Once you've got the machine running, you can repair the /boot/grub/grub.conf file, its drivers in the /boot directory, and the /etc/grub.conf file.
