$ modprobe toshiba_acpi
FATAL: Error inserting toshiba_acpi
(.../kernel/drivers/acpi/toshiba_acpi.ko): No such device
means that I do not have the proper toshiba, in my case, here is what I got:
FATAL: Error inserting toshiba_acpi (/lib/modules/3.0.0-1-amd64/kernel/drivers/platform/x86/toshiba_acpi.ko): No such device
However if one dig a little further
$ sudo acpidump -b -t DSDT -o DSDT.amlYay ! this means I should be able to use toshiba_acpi ! TOS1900 is the Toshiba Value Added Package from windows.
$ iasl -d DSDT.aml
$ grep TOS1900 DSDT.dsl
Name (_HID, EisaId ("TOS1900"))
