Good point, I missed the pr_info("EEEPC WMI: Unknown key %x
pressed\n", code); call.
Then I think this version is ok, I'll add it to acpi4asus tree in a
new eeepc-wmi branch.
Maybe we can get it merged in 2.6.34 thanks to the "New driver exception".

But it might confuse users, as it only support hotkeys and
eeepc-laptop support more stuff,
so it may also be a good a idea to wait for more features before merging it.

Matthew what to you think about it ?
Thanks,
