Dell XPS 13 ("Sputnik") no longer working with fedora kernels >= 3.10

[Dennis Jacobfeuerborn]

Hi,
i seems something in Kernel 3.10 broke the intel display driver for the 
Dell XPS 13 (a.k.a. Sputnik). I filed a bug here:

https://bugzilla.redhat.com/show_bug.cgi?id=995782

Sombody commented in the bug that since it's hard to find other reports 
of this elsewhere this might be related to fedora specific patches to 
the kernel.

I had to fix up my grub config to not always boot the latest kernel to 
make my system usable again and for now I'm stuck on the last 3.9 kernel 
because of this.

Does anybody have an idea for possible workarounds maybe?

Regards,
   Dennis
