Sorry, this is not possible with today's BIOS and EC as I am aware. I'll inquire about this for the future though.

This is a bit surprising to me.  Completely non-working?  Or similar problem to what's getting fixed in the BIOS update we discussed above?

Yes, if you're aware of any models that are not fixed by the BIOS update this month, I would be interested to know.  A majority of our hardware does undergo testing with Linux during development, so usually these types of things are caught.  Once we declare a BIOS stable it's a much lengthier process to issue future fixes however.
