GPU offloading to the nVidia GPU works with bbswitch and bumblebee with the free nouveau driver. Additionally, you can choose to use the nVidia GPU at all times in the BIOS, however, it has a huge impact on battery life. Bumblebee and bbswitch are suggested in order to get the full battery life, otherwise the nVidia GPU is always running and the fan kicks on more than it's supposed to (it barely ever kicks on to begin with). Stock wi-fi card requires non-free firmware to operate. I've replaced it with an Atheros card (AR9285) and it works just fine without non-free firmware. Progress has been made and the Broadcom 4353 802.11 ABGN is now operational under brcm80211(brcmsmac on some debian-based systems). Stock bluetooth card works perfectly without non-free firmware. Changing the AlienFX lighting is not yet supported by a libre program, however, it is not mandatory. Changing the AlienFX backlighting does not work "Out of the box" on any distribution I know of, however a GPL'ed solution is available here https://code.google.com/p/pyalienfx/ from this gentleman. It is very straightforward to install and configure and I have encountered no trouble with it. Other than that, everything else works perfectly with a libre GNU/Linux distribution.
