sleep problems on Panasonic W2 toughbook

sleep problems on Panasonic W2 toughbook

[Alexei Gilchrist]

Hi any help would be greatly appreciated, even what I should be looking at.

Most things work under linux on the Panasonic W2 toughbook except power management (neither APM nor ACPI).
I'm Using kernel 2.6t9.

Problems:
 
Screen dim/brightness do not work, switching to external screen doesn't work.

My main problem though is waking the machine:
S3 will put the machine to sleep OK. Hitting the
powerbutton 'wakes' the machine in that the system and network comes back
but the screen/keyboard/mouse remain dead (no backlight either).

Some things I've noticed:

* The access light for the SD card reader remains on after trying to wake.

* ACPI lid and powerbutton events no longer register at /proc/acpi/event

* This gets logged to the console after it wakes (via network connection):

  # qutrit kernel: MCE: The hardware reports a non fatat, correctable incident on CPU 0
  # qutrit kernel: Bank 1: f200000000000111

* /var/log/messages:
