Are you sure?  The only code that prints that message is in a sysctl handler.

I tend to agree that we should regularly poll the sysctls by some mechanism
like a sensor framework.  We do provide the throttle_log sysctl and a devd
event for the throttle and critical thresholds, so there is some notification
apart from the console message.
