To be honest, this is not going to work very well from a "professional 
audio quality" point of view. Current jack does not support the use of 
multiple backends, and that's not going to change for jack 1.0. For jack 
2.0 it will be possible, but that's not for soon.

However it is possible (what isn't?). Start jack the way you normally 
do, then launch the "alsa_out" tool installed along with modern jack 
installs. It will present your alsa device as a jack client to which you 
can connect ardour.
