That's a slightly different monster all together:
Boot up with your install CD, enter rescue mode, and get to a command prompt. Edit /etc/passwd, and remove the "x" in root's entry:
Save, exit, reboot, and this time when you login there will be NO root password, so immediately do the above instructions and set a new root password.
