It's already in CVS.

It's already there. See the CS4236_IEC958_ENABLE.

Done.

If you want to change the order, there are two functions in ALSA library
for control/names sorting:
hcontrol.c:static int get_compare_weight(const snd_ctl_elem_id_t *id)
simple.c:static int get_compare_weight(const char *name, unsigned int idx)
Probably, it would be better to make these sorting tables configuration at
run-time (store default configuration to /usr/share/alsa/mixer.conf etc.).
