Do you have any numbers on what the added latency is for powersave mode, and
a rough idea of how quickly chipsets will drop to low-power? It may affect
usability a lot if it's "adds 10ms latency after 100ms idle" or "adds 100ms
latency after 5 seconds idle" or some other pattern...

(The chipset in my laptop claims to be an 82801G with 4 PCI-Express ports on
it - I'm trying to get a rough idea what usage I'd get out of that feature..)
