Conky and Nouveau Infos

[FrankBKK]

I prefer to use Nouveau instead Nvidia drivers.
AFAIK Conky does not support Nouveau directly nor does it provide proper vars for it.

So far I managed to pull Memory, Fan and Temp data to use with Conky via glxinfo and hwmon.

For GPU-Frequency and -Utilization I did not found any data yet.
Anyone knows how to pull these infos from the system ?
