Looks like they're bringing forward some fixes that the regular kernel is more cautious with. That makes sense, because they only have to worry about one set of hardware. There are PPAs with the patched packages:
Hm, I guess it's better seing that it's Canonical doing the patches although I would prefer for these things to be part of the upstream kernel or at least of the official Ubuntu ISO.
Right now the http://hwe.ubuntu.com/uds-q/dellxps/ link warns you "this image is not considered an official Ubuntu release"; "this image is for demo purposes only". Not very reassuring.
This makes it unclear if I can actually buy this thing (in Europe).

Why isn't this in the official Ubuntu distro? I don't trust binaries from Dell.
