IMO it should be sufficient to use the already provided Asus hotkey
model identification.
Using dmidecode to check for Asus and then fallback to the default model
if the model is unknown (which does not work for a lot new Asus anyway?)
sounds like the wrong way for me.
Better to have a not supported system (it's easy to white list an
additional model) than to fall back to default and have a broken system
(reading/writing to wrong EC registers,..).
