After much head-scratching, my problem turned out to do with USB 3.0. Here are the findings. The box wasn't waking up prematurely, it wasn't going into sleep at all, which makes the original question somewhat irrelevant in my case.

Suspend now seems to work in Ubuntu (not been using it long enough to know if some subtle problems remain).

I've been having exactly the same problem in Windows 7 and, curiously, disabling USB 3.0 didn't help that at all. Suggestions are welcome.
