Wow, certainly more than expected !? Did you have 550 WPS attributed
to "nvidia" before the change ? Nvidia's supposed to wake up once per
screen refresh : I had 60 WPS (and yes, the xorg driver option reduces
them drastically).

Unless nvidia was interacting with something else on your system ? I'd
be curious to see powertop output with and without the xorg option.
