...30 GB and no backups?

Why would you do this? What's wrong with tar/cp?

Any more details regarding the crashes? log messages, sysrq-t available?

Ouch :(
Not much you can do here. I'd take a first look with "file /lost+found/*"
to see if there's something useful in there. ext2/3-recovery tools are 
out there, but I guess you'll have to try a few and see if they can 
recover anything:

  - e2undel, recover (both available as debian packages in unstable)
  - R-Linux, a free (as in beer) recovery tool for win32 (works pretty good though)
  - ...and then there's always grep(1) & friends :(

make bzImage, not war
