Hibernating Problems Ubuntu 10.10 / T61

Update 2010-11-03: the problem isn't solved reliably … works only "sometimes". Seems to be a kernel problem, see here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/661711

The hibernation problem ("moon" LED blinks, blinking cursor in the upper left corner, no activity) is solved:
