Forget it, it is built into the Kernel, that's exactly what I needed to know. If there is no folder, then there is no vga_switcheroo enabled because it cannot detect the switcher.

I think you are stuck in that mode: if you want to use Ubuntu, you should start from a shutdown rather than restart, it should be fine all the times... I don't either want to suggest you to touch boot settings because it may break your OSX install.
