Would it be beneficial if the device h/w targeted by the "real" Rust
driver has QEMU emulation? Perhaps in addition to physical silicon.

If developers don't need access to physical hardware, they might be
more likely to get involved with Linux/Rust.

Also, I'm guessing QEMU allows us to embed the emulated device into a
variety of board architectures: x86_64, arm64, powerpc, etc. which
could be useful in smoking out architecture-specific Rust driver
issues.
