I believe it's the script at https://lists.gnu.org/archive/html/gnewsense-dev/2010-03/msg00076.html.

I've tested hibernation using pm-hibernate in several situations:

• running "mplayer -vo x11 tv://" with camera disabled: hibernation works, the camera is disabled afterwards, needs Fn-Esc to enable; the script suggests it preventing hibernation, I don't see anything there that would reenable it when resuming so it's probably ok
• no problems with Ethernet connection
• wifi needs rfkill unblock wifi or Fn-F5, otherwise works
• no touchpad problems

Most problems listed in the script are fixed, we could include a much simpler script to unblock all rfkill interfaces instead.
