The timeout is in fact enabled, just hidden inside the getch() function. You should be able to simply change the value of MAX_TIME_COUNT and recompile. You might need to find the right version of avr-gcc to keep the code under 1024 bytes. I think I've had luck with 4.0.2. Also, yes, you can just replace the ATmega8 with an ATmega168.
