These look good to me and they work on my desktop. I will backport this along with several other fixes that are currently in git head master to Gentoo's 0.6.0-rc11 packages tomorrow.

@ryao since you guys did all the hard work I'm reviewing these changes now. I expect to get them merged by Monday so you might just want to wait.

Thanks for the patches. They applied clean and no issues under 3.6.2 .
