I'd prefer to have something kind of unique. Not every pcie card has i2c bus on it. If card is on pcie it would be best to name it as it is common for pcie. InfiniBand would be named according to ib conventions, etc... If that is impossible, I guess we can live with card<something> but... Pavel -- http://www.livejournal.com/~pavelmachek
