Another important note: This driver does not work on all Toshiba laptops, particularly those models which seem to have a BIOS or other firmware which was not developed by Toshiba itself. New reverse engineering work will have to be done on these machines, or Toshiba will have to disclose the necessary details. (For support of machines with Phoenx BIOS, try the [Omnibook driver].) The error you will see in this case is:
$ modprobe toshiba_acpi
FATAL: Error inserting toshiba_acpi
(.../kernel/drivers/acpi/toshiba_acpi.ko): No such device
