No Acer hardware - no acer-wmi.

The driver is working fine. If RFKILL is not enabled in the kernel, then
the LED setting part cannot be called, thus we do not expect it to work.

As far as I can tell, dell-wmi does not support your hardware. Perhaps
you should take that up with the author of that module. He likely has
not yet seen a box like yours.
