Actually AVRDUDE does not check the signature bytes at all, other than
to check that they are reasonable and it looks like a chip is on the
other end.  It's up to the person running AVRDUDE to correctly
identify the chip on the command line.

While this feature could certainly be added, it's never been a high
priority and, for me at least, I would consider this to be in the
"bells and whistles" category.  If it was added, then -p option would
become redundent or at least maybe made optional.
