I've recently managed to get hold of some DSDT dumps from a Panasonic CF-W5 and they've changed the CD power management methods so as it stands the patch will only work on a CF-W4 (and possibly older models). I'm currently trying to get a contact at Panasonic in Japan to see if they can provide some documentation. If not, at the very least a more generic approach that would work would be to call _EJ0 on the OPTD device for power off, but I've not been able to figure out from the ACPICA documentation how I can search the device tree for an OPTD device.
