Details:

The file iom644.h contains the line:
#define SIGNATURE_2 0x09
This definition is true only for the ATmega644, but NOT for the ATmega644P.
The file io.h includes iom644.h for both MCUs, so, if you compile for
ATmega644P, the definition is wrong and should be 0x0a.
The files iom164.h and iom324.h do not contain any signature definitions.

The signatures for the ATmega164P (iom164.h) are (taken from ATMEL doku):
#define SIGNATURE_0 0x1e
#define SIGNATURE_1 0x94
#define SIGNATURE_2 0x0a

The signatures for the ATmega324P (iom324.h) are (taken from ATMEL doku):
#define SIGNATURE_0 0x1e
#define SIGNATURE_1 0x95
#define SIGNATURE_2 0x08
