Yes, but kmod doesn't work with devfs, because kmod needs access to one of
the /dev special files, which don't jet exist. The devfs then creates them,
without a driver attached, and kmod creates the driver, without a /dev file
attached (and will probably discard it upon failure)
devfsd takes care of first creating the /dev file and then calling modprobe.
I hope that this part will someday be packed into kernelspace, and devfsd
