xorg-server has a nasty mouse acceleration bug. I fixed it a while ago, but they haven't said anything yet. Here's the URL to upstream bugzilla, with the patch. It would be awesome if the patch could be included in the ebuild.
Forgot the link... https://bugs.freedesktop.org/show_bug.cgi?id=13808
Javeed, I'll be happy to incorporate the patch as soon as it's committed upstream. Please reopen this bug when that happens. You might want to change the upstream component to Input/Core.
Upstream says they won't do it until 1.5 since it breaks ABI. That shouldn't really affect us gentoo people though, should it? (And to be honest, I don't think anyone relied on the brokenness of the acceleration infrastructure... in the entire source code, those variables are used only in one function, the one that applies acceleration.)

Yeah it does, because that means people have to rebuild all their drivers after a revbump. It's very painful to make users do that, however easy it might seem.
