[Bf-cycles] CUDA render speed with upcoming toolkit 4.1

I tested the RC2 of the upcoming CUDA Toolkit 4.1. 
To my surprise, this affects render time a lot.
A scene of mine with 18k vertices renders in 2:48 minutes, whereas it 
finished within 44 seconds, when compiled with the Toolkit 4.0.

Same goes for the bmps.blend inside our test svn, much slower with the 
new toolkit.

Nothing to worry about I guess, but I wanted to report this anyways, but 
hopefully it's just a bug in their RC2.
