I don't know -- I think I've only ever successfully used ISO files, and
I think I gave up on some IMG file(s) previously (possibly not just from
FreeBSD) without trying to understand why they didn't work.
Have you tried specifically with a recent FreeBSD mini-memstick.img file?
I'm thinking (esp. given what I see from "od -c < /dev/rvnd0d") that
what's wrong is the vnd(4) driver is (also?) imposing some
mis-interpreted idea about the number of cylinders and heads or
something like that, especially given that "fdisk vnd0" is so totally
confused about what's in there.
There's a definite pattern of corruption anyway -- I just can't explain
it well enough yet.
