I recently upgraded from a Dual 2.0 powermac to a nice shiny 3,1 Mac Pro. I'm running one of the older 23" ADC cinema displays which still works perfectly using the ADC to DVI adapter. With the Powermac, I was able to power on the system by touching the power button on the cinema display. With the Mac Pro, the power button still responds to touch (lights up), but doesn't actually power on the system. Was this functionality removed?
