By fails to sleep, I mean I get a blank screen and it does not respond to any input. I'm not sure where it is when it dies though - what's the best way to figure this out? (how can I make SysRq work on an ibook (which has no SysRq key)). I get this with every 2.6.* kernel I've tried, including 2.6.5. I previously had sleep working on my ibook with a 2.6 kernel, but I've since replaced the (dead) hard drive. I can get my ibook to sleep with a 2.4.24 kernel.
