Without ACPI enabled, the notebooks crash on any power management feature, and with ACPI, they just lock up mid-boot. I'm working on resolving the ACPI stuff, so if anyone has docs on how they've implemented ACPI on the NForce3s for notebooks that'd be great. On a sidenote, the ACPI blacklist does not correctly determine the board in these machines.
