Probably.  But why not boot your FC5 disk 1 in rescue mode?

- At the boot prompt, put "linux rescue".

- Let it mount your root filesystem and its dependents.

- At the shell prompt:

  chroot /mnt/sysimage

- Edit /boot/grub/grub.conf as needed, then

  exit # or ^D from chroot
  exit # or ^D from rescue mode to reboot

- Eject the CD.

That said, I've never seen an update farble the grub.conf, so I'd be
surprised if the solution is that simple.  You may have to rerun the
procedure above, but instead of the edit, do a

  grub-install /dev/hda # assuming that's your boot drive.
