No, there's no part info for it.

It requires a little more, and while this question appears to be asked
once each couple of years, nobody appears to be willing to implement
the extra logic.

If you're using a genuine STK500, it should be possible with moderate
effort to add it.  The STK500 is capable of programming these, but as
these controllers have positive reset polarity, the STK500 needs to be
instructed for that.  That requires a minor addition to the config
file parser to add the respective flag, and consequently some
modification to the stk500v2.c file.  This should be done in a way so
any other programmer type will detect it cannot support the request,
and bail out.

Never trust an operating system you don't have sources for. ;-)
