This has been reported[0] in 2008 by Alexander Beregalov and it was
suggested to set sectorsize to the system's page size. This seems to be
done anyway but even explicitly setting this during mkfs doesn't make the
warning go away.
Full dmesg and .config: http://nerdbynature.de/bits/2.6.33-rc6/btrfs/
Thanks,
Christian.

Ok, I've got a sparc box on the way, and I'll cleanup these errors.
