all the LKM load/unload junk, and don't forget to register the SYSINIT
so that the cdevsw entry is attached.
BTW: I think the way it builds it's /dev nodes on the fly as an LKM with
vnode ops is kinda cute - I guess that'd be one way to solve the devfs
persistance problems.. :-) (ie: have the drivers make the nodes in /dev
on disk directly if they are missing, but leave them alone if present).
