acer-wmi only supports those laptops which provide a WMI interface to the relevant BIOS calls; if a laptop's BIOS does not provide that interface, then I don't intend to support it in acer-wmi.
For those older laptops, the wistron_btns module may cover some of this functionality (or perhaps it could be added there), or alternatively, acerhk could be cleaned up and submitted upstream.
