Then the system must think that all my devices are analog, even IEC958,
because I do not see these checkboxes for any device.

First I press the scan for audio devices bar, and this appears in the
terminal that I am running mythfrontend from (I am running it as root):

2010-07-14 14:06:14.425 ALSA, Error: snd_pcm_info_get_card: Operation
not permitted

If I select ALSA:default, at the bottom it says:

Device supports up to 5.1 (AC3, DTS)

But there are no checkboxes for AC3 or DTS. I can select 5.1 under
Speaker Configuration, and if I then set up a separate digital output
and select IEC958, it works.

But I tell you again: on my system these checkboxes do not appear. At
the bottom it says:

C-MEDIA CMI8788, Analog
IEC958 (S/PDIF) Digital Output
Device supports up to 2.0

...and of course I can't select anything but Stereo under Speaker

If this description isn't enough, I'll try to get one, I'll just have to
figure out how to do that (it's some key press that I can't remember).

Yes, I did that. If I don't do that, then ALSA:default is all I see.
