Hi..

I am not talking about the minute details here... for example I didn't like
the way overclocking support is implemented... It has to be a bit more
framework oriented then driver...

What I am thinking right now is if it is worth to add both the features
you are trying. i.e. overclocking and LAB..

So, requested you to give some figures... of ondemand with and without
overclocking... Leave LAB for now...

Then we can give LAB a try with above...
