right now with 2.6.30-rc7(I'll have to load
*-rc8 in the next few days)
Everything seems to be running o.k.
(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.
