This should work, but if you're using LVM there may be an easier way.
Are you using LVM?

If /dev/hdc2 is the new root, you'd want "root=/dev/hdc2"; the "LABEL="
syntax instructs the kernel to read the filesystem labels to find the
root partition. Alternatively you could create the new root filesystem
with a different label (e.g. "newroot") and then change the grub.conf
entry to have "root-LABEL=newroot".
