One kernel thread is about as costly as one userland thread. And I believe we should not design new code that _needs_ polling. I think it is better to have kernel thread than userland polling us all the time. Now... on PC it will be "interesting". Your solution has great advantage of being able to work with s2ram quirks... But s2ram quirks are not an issue on embedded hardware or OLPC, and hopefully kernel mode setting will fix it on PCs, too...
