Unplugging and replugging it fixes the problem. A keyboard is also plugged in, which works normally every time. This has been happening on and off from about 2.6.30-rc* but in 2.6.31-rc* seems to be getting more frequent. Here's the suspend-resume-replug part of the dmesg. Not sure if it is enough, I'd be happy to provide more info.
