Crazy as it seems, add an init script to rmmod psmouse before you
shutdown or reboot linux. Somehow having it loaded when the machine
shuts down causes the BIOS to get upset.
Works on my nc6320 as a workaround, although I've got a few odd issues
still:
Critically, when the lid-switch is pressed, the backlight extinguishes,
but if the touchpad senses any movement, a key is pressed, or for some
random reason, the backlight fires back up again, then doesn't switch
off.
This leaves the laptop very toasty if you shut the lid and it does this.
Does yours do this?
Suspend doesn't work out of box, I've not really tried to diagnose.
