Ah, dediprog... you happen to have the one programmer that is hard to
support.

That is expected, native 4-byte instructions are tried first but they
are not implemented yet for dediprog. It should fall back to another
instruction though. Unless the dediprog resets the chip between in-
structions, it should actually work. Though, David seemed to have
trouble with that too, I didn't test it myself yet.

Can you please just post the whole log (best taken with -o logfile).
