I got the bright idea to use a few free minutes to put the hard drives
from my kids' machine into mine to try to fix them with disklabel
(another long story).  The MBR has been fouled up by an old gateway
machine. 

Unfortunately, the odd behavior of those drives damaged lilo, which
was still the bootloader on this machine.

Borrowing a floppy drive, I then tried to load the old tiny emergency
debian installation so that I could rewrite lilo.  

Bad move.  It tried to mount some of my partitions as ext2.  Only /
survived, and I really only care about home.  Particularly, about 1
directory on home, my dissertation and its graphical files.  The most
recent electronic backup is (we believe) 2 to 3 weeks old.

When linux does this, it does something to the superblock.  I get 
messages from fsck such as:

BAD SUPERBLOCK: MAGIC NUMBER WRONGioctl (GCNIFO):
invalid argument
fsck: /dev/rwd0s6: can't read disk label

How do I recover my data?
