There's an error in the avrdude.conf file.  Edit the section about the
ATmega8515 that is named ``memory "calibration"'', and change the line

        size            = 1;

into

        size            = 4;

Sorry, nobody reported that problem before.

I just fixed it in avrdude's CVS.

Forget about the signature byte.  I wonder why Atmel emphasizes that
implementation detail so much.  As your case shows, this only confuses
the users.

The signature bytes are the signature bytes, and for the user of the
chip (or of avrdude), they have no relationship whatsoever with the RC
oscillator calibration bytes.
