Something I've wondered: is there a way to buy a barebones PC (or even just a motherboard) with an Intel Core M processor installed? Presumed experience level: I'm willing to write an ACPI DSDT from scratch for it. :)
Maybe this would fit your usecase? It has an Intel m3-7Y30 onboard.
I question their commitment to this space though.
Out of interest, why would you need to write a DSDT?
