I had a think about what might have changed when it started freezing again and remembered that I had switched X back to modesetting at a time which would roughly correlate with this (I had been using intel(4) to cope with vncviewer problems, and switched back after jcs enabled SHM in vncviewer). I've moved back to intel(4) now to see if this removes/reduces the problem. Haven't run into one since, but it's still a bit early to say if it's actually helped. (intel does remove one other annoyance, for some inexplicable reason context menus like the right-click menu in browsers often show up on the wrong monitor with modesetting..).
