Do you have the "High Speed Kernel"? When I ran those patches the battery was unstable when it got low. I would get a low battery and then a crash, usually before I could stop the offending activity ( Video playback usually ).
As for the other comments I would say I have lost my stomach for items that cost hundreds of dollars that end up a ... distraction for a child.
The wife is sleeping right now and they are going to be starting the pictocin soon.
