I thought I'd give a few lines to explain the resolution for the benefit of

The reason why vgchange -a -y didn't pick up my VG is due to a small bug in
vgcfgrestore, which only restored the UUIDs of 8 out of my 9 PVs (quoted
from memory, sorry if I got this slightly wrong).
Either way, the fix it to upgrade to a newer version of the lvm tools (from
CVS or the next snapshot)

The reason why I tried to restore it in the first place is that any kind of
partition access on that VG would hang the machine.
The problem turned out to be the crappy VM in 2.4.17, and not LVM.
Actually 2.4.14 also had a few issues fscking the 800G partition, and froze
when fsck was going to write the changes to the partition (and its 4
snapshots)
It probably would have completed had I deleted the snapshots, but I ended up
going back to 2.4.7, and after an 8H fsck, the partition was mountable
again.
Again, thanks to Heinz for his invaluable help.
