I've been following this thread on the xorg-devel ML, and I have those
patches queued for testing ;)

If you pay attention to https://bugs.freedesktop.org/show_bug.cgi?id=11432 I
had published there a patch (comment #23) there that has been happily
working for me since I post it (yet it works). But what it does is ugly and
has drawbacks as explained there so I still consider it a workaround and
not a final solution.

That's the reason I came here, to check out wether the Linux kernel could
address the issue.
