[05/11/2010] Fedora 14 / Ubuntu 10.10 already with vgaswitcheroo!!
From now on, if you want to use the vgaswitcheroo module you just have to install (or test from a Live CD/USB) Fedora 14 or Ubuntu 10.10 (sure, other distributions may also do the trick) and go directly to point "(2) Run the new kernel and test:" from previous post. That's all! I personally have installed in my laptop both Fedora and Ubuntu and they both work perfectly well although there are some differences in the scripts (when I have some time I'll make a specific HowTo for each of the new systems; in the meantime, please write me if you have any doubts). Good luck and I hope you enjoy your hybrid graphics on GNU/Linux!
So just download Fedora 14 or Ubuntu 10.10 and try it for yourself:
