There's a slight problem with ATMega644P and ATMega644 in the iomxx4.h header file. ATMega644 has only one USART, which is correct, but ATMega644P should have two USARTs. avr-libc seems to see both devices as the same device which they apparently are not. Even the paratetric product table at www.atmel.com says that ATMega644P has only one USART, but the datasheet says otherwise.
