does anyone know of a data recovery program for linux that can read raw data from a broken jfs filesystem and grab files out of it?

i hate harddrives... :bang head

The very first thing you want to do, space permitting, is make a bytewise copy of each of the important partitions of the drive, to ensure that you have the best possible chance of getting your bytes back. The downside is that you need enough space to hold whichever partitions you're copying. The upside is that it only requires a single command. The command is dd if=/dev/DYING_PARTITION of=/some/backup/file .
Once that's done, you can see what jfsutils (http://www-124.ibm.com/developerworks/oss/jfs/index.html) has to offer. IIRC, their tools are a little non-standard, but they've got man pages. ;)
