It is still easy:
emerge bumblebee
rc-update add bumblebee default

That's all I did and it works.

With Linux, I just add "optirun " in front of the command in the program-menu 
item.
On MS Windows, I need to:
1) Start the program
2) Stop the program
3) Configure the driver to use the NVidia chipset for the program (It doesn't 
show in the list before I start it once)

And for a lot of these, I need to redo it every time I update the drivers.

If there is a powerful Intel GPU. But those don't come close to the specs 
NVidia and ATI put into the real GPUs.
