I think both implementations still suffer from one-byte-at-a-time IO
operations.  I've modified that for the JTAG stuff to user larger
blocks where appropriate, but I didn't have the time and energy to
merge that back.

Hmm, ISTR I've once got a patch from Bernd Walter implementing
STK500v1 block IO but somehow that got lost.  I've anyone's curious
about adding it, I can dig it up.
