Mmm, I wrote it, but that doesn't mean I know how it works. ;-)

This just allows the module to attach. Unless you define the other fields in
the struct, it won't actually do anything much.

The other fields in the structure are the names of the methods in your ACPI
tables which twiddle the LEDs and set the brightness and so on. If you do an
acpidump, you can read through your ACPI tables.

I've not managed to find any definitive way to find the parameters. Just
grepping through the disassembled tables seems to be the only way.

Have you taken a look at the Linux acpi4asus project? In the past, I've tried
to stay in sync with them, but it's been a while since I last took a look at
their code. The fact that I don't have a functional Asus laptop anymore has
something to do with that.
