P.S. I bought one of these cards the other day, but I haven't got it all
set up yet, which is why I'm not so much help. But this page
http://alsa.opensrc.org/index.php?page=SBliveCapture

says how to route the rendered midi audio back to one of the alsa capture
devices (should just be alsa_pcm:capture_1, alsa_pcm:capture_2). So if you
can get this working, you could just set up a track in ardour with those
as the inputs.

If you go for the softsynth method, fluidsynth uses the same soundfont2
files as the SB Live, which might be handy.
