(how can I make SysRq work on an ibook (which has no SysRq key)). No, once the screen is off, there isn't much you can do. I suggest you do some experiments in console mode, use "snooze -f" (that will bypass pmud or pbbuttonsd, which tend to cut the backlight early). Also, did it die on sleep or on wakeup ? That is, did it reach the sleep state where the led starts "snoring" ? > I get this with every 2.6.* kernel I've tried, including 2.6.5.
