	Bummer.. Really grabbing at straws: What might happen if you
booted the machine with a rescue disk that ran a kernel from RAM
then use dd to copy the contents of hda6 to another clean drive
fitted, temporarily, in the machine?? Since hda6 is a virtual
partition, copying it to a primary partition may work?? Depends on
how important that partition is I guess..

	If all those superblock backups are corrupted, it seems
nothing would work though.. I don't think 'sfdisk' will help in this
case either.. Good Luck..
