The Dell XPS 14 Ultrabook - l421x works out of the Box with openSUSE 12.3 here and also Ubuntu 12.10 and 13.04. Only the WLAN reception is worse than on my other Laptop, but this is also the same on Windows 8 (Dual Boot). Even Bumblebee, Primus and Secure Boot are working.
Powertop claims 12W which I will try to tune down further. Using TLP on Ubuntu (and Bumblebee) it is possible to get Watts down to just 8-10W.
