Yep :)

So as long as I don't use devfs I don't need it. Currently I still use
the /proc interface but I don't have concrete understanding of the
difference between the two yet. fromwhat I gathered you have to specify
devfs in the kernel for it to be used. Is that correct?

Anyway I definitely use multiple cards so I will do the change if
neccessary.
