I can't see anything particularily odd about this partition BTW; I'm not
sure what a LVM superblock is supposed to look like but what's there
*seems* to be likely to be something.  Is the partition table supposed to
have some sort of flag in it (apart from the type=0x8e) saying "I'm an LVM
PV" or is it likely the data (my /usr and /home :( ) in the PV is gone
forever?

If it makes sense to anyone, the first 4kb (and 512kb is in the same
directory) of that partition is at http://fias.co.nz/lvm/sda6-4k

BTW: I'm running LVM 9.1_beta2 (I *think*; whatever came with kernel
2.4.7, anyway).

Thanks
