[linux-lvm] getting pe_start right

While trying to convert my mdadm raid5 array from metadata format 0.9 to 
1.0, I forgot to specify the version and it defaulted to 1.2, which 
damaged the lvm metadata.  After correcting mdadm to 1.0, I decided to 
try to recreate the LVM after managing to locate the volume descriptions 
in the metadata after manually dumping it.

The problem I now have is that pvcreate will not use the same pe_start 
as before.  It was 384 and it is now 3072.  I tried using --metadatasize 
192k --dataalignmentsize 0 and it did not help.  What gives?
