OTOH, longname can be really ugly to read, and it can vary because it
often embeds address or irq numbers in the string.

If a general name is the goal, how about using shortname instead?

Or use id field, as Jaroslav suggested, but without the card number
suffix; then it's unique among multiple cards.
