I don't know of any mkfs changes, but Henk Schoneveld told me once  
that using the mount option "allocsize=512m" reduces fragmentation.   
I've been meaning to try it but haven't gotten around to it yet.   
MythTV tends to keep filesystems very close to full, and I've found  
xfs with default options will fragment and suffer reduced performance  
under these conditions if xfs_fsr isn't run periodically.
