Note that the simplest way is to rename the card identifier using udev 
or a custom script at boot and do not mangle the slot indexes:

   ALSA: add /sys/class/sound/card#/id (r/w) and card#/number (r/o) files

http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=9fb6198e8c574c6547fbfac0ae1eaf7894ddfdcc

The usage is just simple. Everywhere where card index can be used, the 
card name can be used too, for example:

aplay -D hw:0,0 ...

might be:

aplay -D hw:CARDID,0 ...

Someone should update the wiki to add this preferred possibility.
