It takes no time when you already have a complete kernel tree :-) 
You can just apply the patch, type "make" and your're 
done within a minute.

Otherwise, if you plan to recompile a few times more, setting up
ccache could be a good idea.

Well done!

Unfortunately, I have no nvidia graphics to test your work. But I'm
shure the ones with problems here in this thread will give you
some feedback.
