Also while we're at reworking how all this is exposed to our broken
userspace, I wouldn't mind putting all these dev entries under a
directory, if I can figure out how to do that (I haven't really looked

/dev/fsi/{cfamN,sbefifoN,occN, ...} and possibly similar by-id and by-
path that other subsystems use, so we have something more deterministic
than the "random number" crap we do now.

We can always keep hacks to do symlinks in our kernel tree until we
have converted all our userspace users.

We currently control the only userspace users of this, so now is a good
time to cleanup how we expose things. This won't always be the case.
