When I was testing with the nvidia driver I did spend some time watching Powermizer to see if it was able to idle more often, but couldn't see an obvious improvement. Powermizer successfully clocked down to low power mode in all cases when /fairly/ idle, with or without the fix. No I haven't noticed the lag when the Powermizer raises the clock again. But I did only test nvidia for about an hour...
