Hey zbiggy,

nice to read you, pal! Can you link to specific bug reports about the
above issue? I've build with vdpau enabled, and my gpu's (two geforce
9800 gt in SLI mode) are between 47 and 60°C - usually 54°C which seems
to be okay. Maybe that issue is fixed already?

Do we need the vdpau module at all in linux, if nvidia ships with it's
own?

thanks,
jean
