It would be nice if the tests paid some attention to timing, though
QEMU does not implement many timing issues either.

The benefit from this setup would be that the test suite would be
validated against real HW. But as the hardware gets older and breaks
down, it will be increasingly difficult to validate the suite in the
future so I also think it's probably not worth the effort.
