[Brett Howard <brett@xxxxxxxxxxxxxxxxx>]

just for another data point... I just switched to speed mode and
rebooted.  the open source Nvidia drivers actually just fired up and
the system seems to be running fine at full resolution.  I'm unable to
adjust display brightness but with only firefox open (typing this
email) and my default boot I'm drawing about 24.2 watts with all
powertop tunables enabled.

Not sure if any of this helps but just thought I'd throw this out there.
