Never assign bugs to ubuntu-core-dev; it spams all of us, many of whom have little experience with or clue about the kernel or xorg. In fact, generally in this bug tracking system you shouldn't set the assigned-to field at all unless you're a developer, are managing a developer, or are asked to by a developer, since it indicates that somebody is actually working on the bug at the moment.

I'll send this off to the kernel folks instead.
