I have just one other observation, I found a funky tool a while back called toshctl, it has the following... bios.date: 1026309600 bios.id: 64615 bios.version: 2.00 TOSHIBA hci.cpu_speed: 1 hci.fan: 1 hci.lcd.backlight: 1 hci.lcd.brightness: 7 hci.lcd.mode: 2 hci.lcd.type: 4 hci.power_source: 1 hci.select_bay: 4 hci.software_suspend: 1 If you haven't looked at it it's definantly a worthwhile tool.
