I have been the latest kernel out of hardy-proposed and the machine has been running for 3 hours 45 minutes, most of which has been idle - and no problems, scree blanked and machine cool to touch.
Opening and closing the lid works fine.
As a final test, tomorrow, I shall leave the current kernel on and remove the pipe-A option and see if the freezes reoccur as a confirmation.
