A full linux environment (with external monitor support) sounds awesome. I hope that enabled KVM becomes standard

Would graphics acceleration work properly?

Depends on the kind of acceleration you want. VirGL is available on Linux host/Linux guest setups with recent kernels, not sure if QXL/SPICE will be available or can be added to the userland. Can't imagine a hardware passthrough situation making sense on a phone/tablet, either.

You can already to that with termux, XSDL and some scripts. No virtualization needed.
