Had smiliar problems with ATmega chips. For your convenience Atmel set the default clock very low (1meg?). So you can't talk to chip at 3.69mhz. Lower the clock to as low as it will go, and make the isp clock less than 1/4 of that. Set the clock bits to 4mhz or better, then set STK500 back to 3.69mhz and then you can write program to flash.
