It is not just nvidia.
I'm using two plain old PCI Matrox G400 and whenever I start X with
powerd enabled I have a full freeze within 24 hours.
It doesn't seem to be a problem to start powerd once X is runnning.
Maybe it is something like tuning some delay loop with reduced clock
rate, which then isn't long enough with increased speed.
