The "auto-restart" problem is usually associated with an attached USB hub, or the optional "Restart automatically after a power failure" block is checked in the EnergySaver Control Panel or Prefpane. I did have the problem after I installed Tiger and had not removed my M-Audio Revolution 7.1 sound card. Once I pulled the card, erased M-Audio software, a checked the permissions, the problem went away. That particular bug was mentioned on MacFixit.com.
