I seem to remember seeing in the changlog for ICS the ability to open the notifications from the lockscreen. On my Stock TP, this doesn't work. I have the "slide" unlock setting currently enabled. Any help would be appreciated.
Do you have a pattern lock or PIN? I seem to remember being able to get them on the lockscreen before I created a pattern lock. Now, I cannot either. I don't have it in front of me to test it out, but see if that is the case.
