Comment 19 for bug 319210

The upstream commit ea309e47457156b60aadbf113f04e5b6851029c8 (proposed for 1.6 branch) promises to fix this issue. I have Jaunty xserver-xorg-core packages with this patch in my PPA https://launchpad.net/~tormodvolden/+archive/ppa and can confirm that it works fine on (unpatched) savage.
