This turned out to be something unrelated.  Turns out, the algorithm
for the stk500 never did work for any non-paged device, i.e.,
non-ATmega part.

The AVR061 protocol seems a bit unclear on this, but it seemed to
imply that the "program page" command works for non-paged parts.
Thus, as an optimization, if the selected programmer supports this
command, 'avr_write()' would always use that, instead of programming
each individual byte.

Well ... it looks like this is not the case.  Since the 8515 is does
not have a paged memory, it failed.

Ted ... please try again.  Programming is going to be pretty slow.
Also, the algorithm needs some work because the way it is working now,
it is issuing the raw serial programming instructions to the STK500,
and not using the "program flash" command.  As a result, parallel
programming is not an option for non-paged parts at the moment.  I'll
have to think about this.
