It links into the kernel as a module.  All modules that link into the 
kernel must be installed as root, only that way can it get real time 
support as well as device access which is not directly available to user 
space drivers.  Linux Device Drivers by Rubini covers this topic fairly 
thoroughly and I highly recommend the read (although the kernel 
discussed within is very outdated now).
