You can probably boot an install CD and go to the shell. Assuming you can then see sd* at umass (which is fairly likely), you should be able to mount/newfs as necessary, and copy the data from the ami (pax/tar/cp/dd are available).
Or if you have another system running that you can save a backup onto you can easily run dump piped over ssh.
