We may still want to use this on older kernels though. If I knew how to add arbitrary sysfs attributes I'd submit a patch right away, but I don't, and I don't have time to research it right now. Anyway, I checked the code, and it looks like my analysis wasn't quite correct, it seems to use snprintf(..., "%s %d", parentname, channel) but channel isn't assigned based on the i2c-bus' reg property but just an arbitrary number, so we'd have to probe both uni-n busses. Which is fine, still *much* better than probing all of them. johannes
