Hi Justin,

the disassembled DSDT always helps as a first step.

1. install "iasl" or get and compile the source:
https://www.acpica.org/downloads/unix_source_code.php
2. cp /sys/firmware/acpi/tables/DSDT dsdt.aml
3. iasl -d dsdt.aml

This creates a "dsdt.dsl" file. This is the interesting one.

Furthermore, check the kernel bugzilla if there isn't a similar bug
somewhere already.
http://bugzilla.kernel.org

This article is also good literature how WMI drivers work:
http://lwn.net/Articles/391230/

Also check for latest /lib/udev/keymaps/ and
/lib/udev/keymaps/force-release/. On this page this helped e.g. on a
Samsung laptop: http://blog.nonobis.nl/?p=11

Cheers,
Sebastian
