Yes, more than likely. However, I think the string-based selection is
the best that can be done right now. It gives us, e.g., pretty-printing
of the backend property so that you can easily check what mode is in use.

The next area of ugliness will be the PIT and its relation to the HPET.
I started looking into this, found some bugs, but do not really have a
nice model for all that yet.

Looking into the remaining remarks now.
