http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=6c31b93a14a453c8756ffd228e24910ffdf30c5d

I'd guess the commit above is related, although I don't see any way for
it to make things interesting without the user doing mount -o inode64.

strace -v should show us more, it would show if the inode numbers coming
out of stat64 are big.
