Hi,
I found a little problem in your driver(ver 0.5)...

> result = acpi_bus_register_driver(&acpi_hotkey_driver);
> if (ACPI_FAILURE(result)) {
>             ACPI_DEBUG_PRINT((ACPI_DB_ERROR, "Error registering hotkey driver\n"));
>             return_VALUE(-ENODEV);
>}
The return value of acpi_bus_register_driver is the number of devices
that were claimed by the driver, or a negative error status for
failure. But ACPI_FAILURE is a macro for checking whether the value is
zero or not. I think using "if ( result < 0 ) {.." here is better.

BTW, I have wrote a user space hotkey handler in Perl, which supported
LCD brightness adjustment now:)
It is available at http://vgod.info/dl/w2d/hotkey
