(even with this error message) under nvidia-settings the temperature is at a comfortable number. There is some issues when watching movies on certain sites(but I think this is gtk+ related) As for the kernel, I didn't check to see is acpi's video module is loading or built-in(will look when I get a chance), quit possibly causing some interference. (but probably not) In any case my main concern with the gpu is to make sure that the temp stays at a good level, and so far It has. -- Justin P. Mattock
