CONFIG_ACPI_TOSHIBA
This driver adds support for access to certain system settings
on "legacy free" Toshiba laptops. These laptops can be recognized by
their lack of a BIOS setup menu and APM support.
On these machines, all system configuration is handled through the
ACPI. This driver is required for access to controls not covered
by the general ACPI drivers, such as LCD brightness, video output,
etc.
This driver differs from the non-ACPI Toshiba laptop driver (located
under "Processor type and features") in several aspects.
Configuration is accessed by reading and writing text files in the
/proc tree instead of by program interface to /dev. Furthermore, no
power management functions are exposed, as those are handled by the
general ACPI drivers.
More information about this driver is available at
<http://memebeam.org/toys/ToshibaAcpiDriver>.
If you have a legacy free Toshiba laptop (such as the Libretto L1
series), say Y.
