as Russell pointed out, this is really odd - some fields
are displayed correctly, others are off with the pixies.
I can't see any obvious pattern either... the only thing
I can think of is that xfs_db is doing some deep and
meaningful bit shifting to come up with these numbers -
perhaps this is a compiler issue (we had problems before
with the xfs_high/lowbit routines on non-2.91.66 compilers,
perhaps this is true on ppc also - its probably worthwhile
trying that compiler to build userspace too if you can).
