Yes, RTC is a pretty clever hack that should not break anything. I also used leds on port 80, hardware debugger, and beeps to get same results. Actually... I played around with idea "enter low-power mode without hardware help".. it could be very useful for driver testing. I imagine something that would suspend all the devices, but instead of powering cpu down at the end, it would just enter low power mode. That way, we can rule BIOS interactions etc. Would such patch be acceptable?
