Robert Hooker has provided an additional patch which automatically switches off the i915.enable_backlight parameter (see comment #18) for the Dell XPS13.

The PPA kernel now includes both patches (as of the ~kamal1 version): https://launchpad.net/~kamalmostafa/+archive/i915-enable-backlight

With the PPA kernel installed, backlight control should work properly on the Dell XPS13 without needing any special boot parameters.
