Hi:

In debugging with some future machines that actually contain BIOS level
support for dell-wmi, I've determined that the upper half of the data
that comes back from wmi_get_event_data may sometimes contain extra
information that isn't currently relevant when pulling scan codes out of
the data.  This causes dell-wmi to improperly respond to these events.

I'm attaching a patch (Exchange would munge up the line breaks otherwise).

Thanks,
