So what's your suggestion to fix the behaviour I was describing? Maybe a
combination of Jaroslav's collision detection together with a logic that
does not touch the id in case it was passed as module option?
I'm afraid touching choose_default_name() will cause a lot of breakage
for users as their card IDs will suddenly change and former '-D hw:xxx'
syntax won't work anymore.
