The point I missed here is "2048 byte sectors".

>turion% dd if=/dev/da0 bs=512 count=1 >/dev/null

Reading 512 bytes from a device with 2KB sectors won't work.  Reading
a 2KB block does work.

My next problem is that mtools is incompatible with anything other
than 512 byte sectors but I'll take that up on a more relevant list.
