Try booting the QuickSilver to your OS-X.4 DVD and use the "Change Password" command to replace the old password with something else and then re-boot. I was able to enter a customer's eMac and recover all the user identities and files by doing a password change from the OS install disk. After confirming that no files had been lost, we recreated the individual passwords back to the originals and all worked well after that.
