My hunch is that for nearly anyone who is serious about it these days, the way forward is either to have unusually tight control over the underlying platform, or to include a servant Linux installation with your OS. If Windows is a buggy set of device drivers, then Linux is a free set of buggy device drivers. If you're happy with your OS running as a client of a Linux hypervisor indefinitely then you could go for that; otherwise you'd have to try to gradually move bits of the hardware support into your OS over time—ideally faster than new Linux dependencies arise...
