I'm curious, why there is CONFIG_LBD on 64-bit architecture?
Is there because of VFS issue?
I'm using Athlon64 kernel with CONFIG_LBD unset and XFS seems to use large
block/inode numbers:
SGI-XFS CVS-2004-10-22_05:00_UTC with ACLs, large block/inode numbers, no debug 
enabled

Is there possibility that parted changes only kernel idea about partition
table but not real disk layout? Did you try fdisk?
