Ouch. That's.. a very embarrassing bug. Actually, I know where it
came from: I was looking at flat_dt.h from dtc, which also gets this
wrong (but the declaration in question is unused). Of course, I also
wrote flat_dt.h ...

Found it, there was a direct use of the position of the length in
_fdt_next_tag(). Just pushed out a fix for this in the libfdt tree,
along with some other small fixes which I found while tracking this
one down.
Oh, incidentally, I applied your patch by eye rather than with
patch(1), which was handy, because it appears to have been whitespace
damaged.
