I haven't changed the partitions for quite some time and many many versions of
the LVM have had a chance to create this.
Personally, I could live with a message like "your PV metatdata is crap, 
please check". Someone less cautious my have just mkfsed over it...

I still have the logs on my old root partition. Below is the the relevant part 
of boot.msg running the same kernel 2.4.17-XFS:

The evmsEngine.log of evms_pvscan is attached. I'll try to recreate the old 
LVs later.
