Dedicated disks from a sparc64/-CURRENT system into an Alpha

Sorry to cross post this, but a suggestion mailed to me off-list regarding 
the problem below suggested that maybe it's endian related.  As I need to 
get these disks working in either an Alpha box or an x86 box and sparc64 
being the 'odd-one-out' (big endian), maybe someone on this list can shed 
some light.
