I finally did a disaster recovery using my Ubuntu Time Capsule replacement. It took about 5 hours to recover a 160GB drive (95% full) over my home network. Started right up and worked like I had left off just a few hours before!
Here's the set up to use:
Start up from the MacOS X disk and open the Terminal from the Utilities menu. Type the following:
mount_afp -i afp://ip_address_of_ubuntu_box/VolumeName /Volumes/YOURDIRNAMEHERE
ls -al ./YOURDIRNAMEHERE
If you find the disk image volume in the listing, you're all set. Exit the terminal and using the Utilities menu you can select Restore from Backup Disk.
