You can use the same major/minor numbers. You can > register multiple cdevsw's per major number with make_dev(); (do NOT > use cdevsw_add() for this). How does this work for all the routines? When you register the "new" minor number, can you be specifying new read/write/poll/ioctl/etc routines? I ask, as my RNG is a kld, and I want it to be as separate as possible without getting ridiculous.
